+ * Build system: Direct support for CMake, find_package(TagLib) exports target
+   TagLib::tag.
+ * Build system: Fixed PackageConfig to support both relative and absolute paths.
+ * Build system: utf8cpp is no longer included, it can be provided via a system
+   package or a Git submodule.
+ * ASF: Support additional properties ARTISTWEBPAGE, ENCODING, ENCODINGTIME,
+   FILEWEBPAGE, INITIALKEY, ORIGINALALBUM, ORIGINALARTIST, ORIGINALFILENAME,
+   ORIGINALLYRICIST.
+ * ID3v2: Fixed extensibility of FrameFactory, use it also for WAV and AIFF
+   files.
+ * MP4: Support additional properties OWNER, RELEASEDATE.
+ * MP4: Introduced ItemFactory allowing clients to support new atom types.
+ * MP4: Detect duration from mvhd atom if not present in mdhd atom.

-TagLib Installation
-===================
-
-TagLib uses the CMake build system. As a user, you will most likely want to
-build TagLib in release mode and install it into a system-wide location.
-This can be done using the following commands:
-
-  cmake -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_BUILD_TYPE=Release .
-  make
-  sudo make install
-
-In order to build the included examples, use the BUILD_EXAMPLES option:
-
-  cmake -DBUILD_EXAMPLES=ON [...]
-
-See http://www.cmake.org/cmake/help/runningcmake.html for generic help on
-running CMake.
-
-Mac OS X
---------
-
-On Mac OS X, you might want to build a framework that can be easily integrated
-into your application. If you set the BUILD_FRAMEWORK option on, it will compile
-TagLib as a framework. For example, the following command can be used to build
-an Universal Binary framework with Mac OS X 10.4 as the deployment target:
-
-  cmake -DCMAKE_BUILD_TYPE=Release \
-    -DBUILD_FRAMEWORK=ON \
-    -DCMAKE_C_COMPILER=/usr/bin/gcc-4.0 \
-    -DCMAKE_CXX_COMPILER=/usr/bin/c++-4.0 \
-    -DCMAKE_OSX_SYSROOT=/Developer/SDKs/MacOSX10.4u.sdk/ \
-    -DCMAKE_OSX_DEPLOYMENT_TARGET=10.4 \
-    -DCMAKE_OSX_ARCHITECTURES="ppc;i386;x86_64"
-
-For a 10.6 Snow Leopard static library with both 32-bit and 64-bit code, use:
-
-  cmake -DCMAKE_BUILD_TYPE=Release \
-    -DCMAKE_OSX_DEPLOYMENT_TARGET=10.6 \
-    -DCMAKE_OSX_ARCHITECTURES="i386;x86_64" \
-    -DBUILD_SHARED_LIBS=OFF \
-    -DCMAKE_INSTALL_PREFIX="<folder you want to build to>"
-
-After 'make', and 'make install', add libtag.a to your XCode project, and add
-the include folder to the project's User Header Search Paths.
-
-Windows
--------
-
-It's Windows ... Systems vary!
-This means you need to adjust things to suit your system, especially paths.
-
-Tested with:
-  Microsoft Visual Studio 2010
-  Gcc by mingw-w64.sf.net v4.6.3 (Strawberry Perl 32b)
-  MinGW32-4.8.0
-
-Requirements:
-  1. Tool chain, Build Environment, Whatever ya want to call it ...
-     Installed and working.
-  2. CMake program. (Available at: www.cmake.org)
-     Installed and working.
-
-Optional:
-  1. Zlib library.
-     Available in some Tool Chains, Not all.
-     Search the web, Take your choice.
-
-Useful configuration options used with CMake (GUI and/or Command line):
-  Any of the ZLIB_ variables may be used at the command line, ZLIB_ROOT is only
-  available on the Command line.
-  ZLIB_ROOT=            Where to find ZLib's root directory.
-                        Assumes parent of: \include and \lib.
-  ZLIB_INCLUDE_DIR=     Where to find ZLib's Include directory.
-  ZLIB_LIBRARY=         Where to find ZLib's Library.
-  ZLIB_SOURCE=          Where to find ZLib's Source Code.
-                        Alternative to ZLIB_INCLUDE_DIR and ZLIB_LIBRARY.
-  CMAKE_INSTALL_PREFIX= Where to install Taglib.
-  CMAKE_BUILD_TYPE=     Release, Debug, etc ... (Not available in MSVC)
-
-The easiest way is at the Command Prompt.
-  MSVS Command Prompt for MSVS Users.
-  (Batch file and/or Shortcuts are your friends)
-
-  1. Build the Makefiles:
-       Replace "GENERATOR" with your needs.
-       For MSVS : "Visual Studio X" where X is the single or two digit version.
-       For MinGW: "MinGW Makefiles"
-
-       C:\GitRoot\taglib> cmake -G "GENERATOR" -DCMAKE_INSTALL_PREFIX=C:\Libraries\taglib
-
-     Or use the CMake GUI:
-       1. Open CMake GUI.
-       2. Set Paths.
-          "Where is the source code" and "Where to build the binaries"
-          Example, Both would be: C:\GitRoot\taglib
-       3. Tick: Advanced
-       4. Select: Configure
-       5. Select: Generator
-       6. Tick: Use default native compilers
-       7. Select: Finish
-       Wait until done.
-       5. If using ZLib, Scroll down.
-          (to the bottom of the list of options ... should go over them all)
-          1. Edit: ZLIB_INCLUDE_DIR
-          2. Edit: ZLIB_LIBRARY
-       6. Select: Generate
-
-  2. Build the project:
-       MSVS:
-         C:\GitRoot\taglib> msbuild all_build.vcxproj /p:Configuration=Release
-           OR (Depending on MSVS version or personal choice)
-         C:\GitRoot\taglib> devenv all_build.vcxproj /build Release
-       MinGW:
-         C:\GitRoot\taglib> gmake
-           OR (Depending on MinGW install)
-         C:\GitRoot\taglib> mingw32-make
-
-     Or in the MSVS GUI:
-       1. Open MSVS.
-       2. Open taglib solution.
-       3. Set build type to: Release (look in the tool bars)
-       2. Hit F7 to build the solution. (project)
-
-  3. Install the project:
-       (Change 'install' to 'uninstall' to uninstall the project)
-       MSVS:
-         C:\GitRoot\taglib> msbuild install.vcxproj
-           OR (Depending on MSVC version or personal choice)
-         C:\GitRoot\taglib> devenv install.vcxproj
-       MinGW:
-         C:\GitRoot\taglib> gmake install
-           OR (Depending on MinGW install)
-         C:\GitRoot\taglib> mingw32-make install
-
-     Or in the MSVS GUI:
-       1. Open project.
-       2. Open Solution Explorer.
-       3. Right Click: INSTALL
-       4. Select: Project Only
-       5. Select: Build Only INSTALL
-
-To build a static library, set the following two options with CMake.
-  -DBUILD_SHARED_LIBS=OFF -DENABLE_STATIC_RUNTIME=ON
-
-Including ENABLE_STATIC_RUNTIME=ON indicates you want TagLib built using the
-static runtime library, rather than the DLL form of the runtime.
-
-Unit Tests
-----------
-
-If you want to run the test suite to make sure TagLib works properly on your
-system, you need to have cppunit installed. To build the tests, include
-the option -DBUILD_TESTS=on when running cmake.
-
-The test suite has a custom target in the build system, so you can run
-the tests using make:
-
-  make check

+
+In order to build the included examples, use the `BUILD_EXAMPLES` option:

+
+See [cmake(1)](https://cmake.org/cmake/help/latest/manual/cmake.1.html) for
+generic help on running CMake.
+
+## Build Options
+
+These are the most important build options. For details, have a look into the
+CMakeLists.txt file.
+
+| Option                  | Description                                        |
+|-------------------------|----------------------------------------------------|
+| `BUILD_SHARED_LIBS`     | Build shared libraries                             |
+| `CMAKE_BUILD_TYPE`      | Debug, Release, RelWithDebInfo, MinSizeRel         |
+| `BUILD_EXAMPLES`        | Build examples                                     |
+| `BUILD_BINDINGS`        | Build C bindings                                   |
+| `BUILD_TESTING`         | Build unit tests                                   |
+| `TRACE_IN_RELEASE`      | Enable debug output in release builds              |
+| `WITH_ZLIB`             | Whether to build with ZLib (default ON)            |
+| `ZLIB_ROOT`             | Where to find ZLib's root directory                |
+| `ZLIB_INCLUDE_DIR`      | Where to find ZLib's include directory             |
+| `ZLIB_LIBRARY`          | Where to find ZLib's library                       |
+| `CMAKE_INSTALL_PREFIX`  | Where to install Taglib                            |
+| `TAGLIB_INSTALL_SUFFIX` | Suffix added to installed libraries, includes, ... |
+| `ENABLE_STATIC_RUNTIME` | Link with MSVC runtime statically                  |
+| `BUILD_FRAMEWORK`       | Build a macOS framework                            |
+| `TESTS_DIR`             | Where to find unit test data (with data appended)  |
+| `TESTS_TMPDIR`          | Where to create temporary files in unit tests      |
+
+
+If you want to install TagLib 2 alongside TagLib 1, you can use
+`-DTAGLIB_INSTALL_SUFFIX=-2` and make sure that `BUILD_EXAMPLES` is not `ON`
+for both versions. The installed files will then include bin/taglib-2-config,
+include/taglib-2, cmake/taglib-2, pkgconfig/taglib-2.pc,
+pkgconfig/taglib_c-2.pc and the libraries have a suffix "-2".
+
+### Compile Time Configuration of Supported Formats
+
+To reduce the size of the library, it is possible to switch off supported file
+formats. By default, all formats are enabled. Support for MPEG files (MP3, AAC)
+and ID3 tags cannot be disabled. The following CMake options are available:
+
+| Option                  | Description                                        |
+|-------------------------|----------------------------------------------------|
+| `WITH_APE`              | Build with APE, MPC, WavPack (default ON)          |
+| `WITH_ASF`              | Build with ASF (default ON)                        |
+| `WITH_DSF`              | Build with DSF (default ON)                        |
+| `WITH_MATROSKA`         | Build with Matroska, WebM (default ON)             |
+| `WITH_MOD`              | Build with Tracker modules (default ON)            |
+| `WITH_MP4`              | Build with MP4 (default ON)                        |
+| `WITH_RIFF`             | Build with AIFF, RIFF, WAV (default ON)            |
+| `WITH_SHORTEN`          | Build with Shorten (default ON)                    |
+| `WITH_TRUEAUDIO`        | Build with TrueAudio (default ON)                  |
+| `WITH_VORBIS`           | Build with FLAC, Ogg, Opus, Speex (default ON)     |
+
+Note that disabling formats will remove exported symbols from the library and
+thus break binary compatibility. These options should therefore only be used
+if the library is built specifically for a certain project. The public header
+files still contain the full API, if you use TagLib with a reduced set of
+formats, you can include taglib_config.h and use its definitions (prefixed with
+`TAGLIB_`, e.g. `TAGLIB_WITH_APE`), as it is done in examples/framelist.cpp.
+
+## Dependencies
+
+A required dependency is [utf8cpp](https://github.com/nemtrif/utfcpp). You can
+install the corresponding package (libutfcpp-dev on Ubuntu, utf8cpp in Homebrew,
+utfcpp in vcpkg) or fetch the Git submodule with `git submodule update --init`.
+
+Optional dependencies are
+- [zlib](https://www.zlib.net/): You can disable it with `-DWITH_ZLIB=OFF`,
+  build and install it from the sources or use a package (zlib1g-dev on Ubuntu,
+  zlib in vcpkg). It is needed for compressed ID3v2 frames.
+- [CppUnit](https://wiki.documentfoundation.org/Cppunit): Is required for unit
+  tests, which are disabled by default. If you enable them with
+  `-DBUILD_TESTING=ON`, you can build and install it from the sources or use a
+  package (libcppunit-dev on Ubuntu, cppunit in Homebrew, cppunit in vcpkg).
+  If the unit tests are enabled, you can run them with your build tool
+  (`make check`, `ninja check`) or via CMake
+  `cmake --build /path/to/build-dir --target check`.
+
+## UNIX (Including Linux, BSD and macOS)
+
+#### Building TagLib
+
+On Linux, you can install the dependencies using the package manager of your
+distribution. On macOS with Homebrew, you can use `brew install cppunit utf8cpp`
+to install the dependencies.
+
+```
+# Adapt these environment variables to your directories
+TAGLIB_SRC_DIR=$HOME/projects/taglib/src/taglib
+TAGLIB_DST_DIR=$HOME/projects/taglib/src/build
+cd $TAGLIB_SRC_DIR
+cmake -B $TAGLIB_DST_DIR -DBUILD_SHARED_LIBS=ON -DVISIBILITY_HIDDEN=ON \
+  -DBUILD_TESTING=ON -DBUILD_EXAMPLES=ON -DBUILD_BINDINGS=ON \
+  -DCMAKE_BUILD_TYPE=Release
+cmake --build $TAGLIB_DST_DIR --config Release
+cmake --build $TAGLIB_DST_DIR --config Release --target check
+
+# Install to ~/pkg folder
+cmake --install $TAGLIB_DST_DIR --config Release --prefix $HOME/pkg --strip
+
+# Run example from installed package
+LD_LIBRARY_PATH=$HOME/pkg/lib $HOME/pkg/bin/tagreader /path/to/audio-file
+```
+
+#### Building a Project Using TagLib
+
+As an example for an external application using TagLib, we create a folder
+taglib-client and copy the file tagreader.cpp from the examples folder
+of the TagLib sources into it. We then add this simple CMakeLists.txt.
+
+```
+cmake_minimum_required(VERSION 3.5.0)
+project(taglib-client)
+set(CMAKE_CXX_STANDARD 17)
+find_package(ZLIB)
+find_package(TagLib 2.0.0 REQUIRED)
+add_executable(tagreader tagreader.cpp)
+target_link_libraries(tagreader TagLib::tag)
+```
+
+To build into a folder `build` inside this directory, just run
+
+```
+# Set this to the path where TagLib is installed
+TAGLIB_PREFIX=$HOME/pkg
+cmake -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=$TAGLIB_PREFIX
+cmake --build build --config Release
+
+build/tagreader /path/to/audio-file
+```
+
+If TagLib is installed in a standard location (e.g. /usr, /usr/local), its CMake
+configuration is found without setting CMAKE_INSTALL_PREFIX (or alternatives
+like CMAKE_PREFIX_PATH, CMAKE_SYSTEM_PREFIX_PATH).
+
+To use the C-bindings with tagreader_c.c, you can change the last two lines in
+CMakeLists.txt to
+
+```
+add_executable(tagreader_c tagreader_c.c)
+target_link_libraries(tagreader_c TagLib::tag_c)
+```
+
+#### Building a Project Using pkg-config
+
+Before version 2.0, TagLib did not export CMake configuration, therefore
+`pkg-config` could be used. This is still possible.
+
+Note, however, that `pkg-config` makes it more difficult to use packages which
+are not installed in a standard location. You can point `pkg-config` to search
+in non-standard locations for .pc-files, but they still contain the install
+locations defined when building TagLib. Since we did not give a
+`CMAKE_INSTALL_PREFIX` in the example above, the default `/usr/local/` is used.
+
+```
+PKG_CONFIG_PATH=$HOME/pkg/lib/pkgconfig pkg-config --libs --cflags taglib
+-I/usr/local/include -I/usr/local/include/taglib -L/usr/local/lib -ltag -lz
+```
+
+The following examples use the same build example with additional CMake
+parameters affecting the installation location.
+
+- Using the default prefix `-DCMAKE_INSTALL_PREFIX=/usr/local`:
+  ```
+  -I/usr/local/include -I/usr/local/include/taglib -L/usr/local/lib -ltag -lz
+  ```
+- Using an absolute prefix `-DCMAKE_INSTALL_PREFIX=/usr`:
+  ```
+  -I/usr/include/taglib -ltag -lz
+  ```
+- Using absolute lib and include directories
+  `-DCMAKE_INSTALL_LIBDIR=/abs-lib -DCMAKE_INSTALL_INCLUDEDIR=/abs-include -DCMAKE_INSTALL_PREFIX=/usr`:
+  ```
+  -I/abs-include -I/abs-include/taglib -L/abs-lib -ltag -lz
+  ```
+- Using relative lib and include directories
+  `-DCMAKE_INSTALL_LIBDIR=rel-lib -DCMAKE_INSTALL_INCLUDEDIR=rel-include -DCMAKE_INSTALL_PREFIX=/usr`:
+  ```
+  -I/usr/rel-include -I/usr/rel-include/taglib -L/usr/rel-lib -ltag -lz
+  ```
+  This is the output of
+  ```
+  PKG_CONFIG_PATH=$HOME/pkg/rel-lib/pkgconfig pkg-config --libs --cflags taglib
+  ```
+  You could add `--define-prefix` to the `pkg-config` arguments to have the
+  effective location `$HOME/pkg/` instead of `/usr/` in the output.
+
+Therefore, the correct paths for our example package would be given when using
+the `--define-prefix` feature.
+
+```
+PKG_CONFIG_PATH=$HOME/pkg/lib/pkgconfig pkg-config --define-prefix --libs --cflags taglib
+```
+
+You can use pkg-config from CMake, however, relocation with `--define-prefix`
+is not supported.
+
+```
+cmake_minimum_required(VERSION 3.6.0)
+project(taglib-client)
+find_package(PkgConfig)
+pkg_check_modules(TAGLIB REQUIRED IMPORTED_TARGET taglib)
+add_executable(tagreader tagreader.cpp)
+target_link_libraries(tagreader PkgConfig::TAGLIB)
+```
+
+#### Framework on macOS
+
+On macOS, you might want to build a framework that can be easily integrated
+into your application. If you set the BUILD_FRAMEWORK option on, it will compile
+TagLib as a framework. For example, the following command can be used to build
+a framework with macOS 10.10 as the deployment target:
+
+    mkdir build; cd build
+    cmake .. -DCMAKE_BUILD_TYPE=Release \
+      -DBUILD_TESTING=OFF \
+      -DBUILD_FRAMEWORK=ON \
+      -DCMAKE_OSX_DEPLOYMENT_TARGET=10.10 \
+      -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64"
+    make
+
+For a 10.10 static library, use:
+
+    mkdir build; cd build
+    cmake .. -DCMAKE_BUILD_TYPE=Release \
+      -DBUILD_TESTING=OFF \
+      -DBUILD_SHARED_LIBS=OFF \
+      -DCMAKE_OSX_DEPLOYMENT_TARGET=10.10 \
+      -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64"
+    make
+
+After `make`, and `make install`, add `libtag.` to your XCode project, and add
+the include folder to the project's User Header Search Paths.

+For this example, we assume that you have the Visual Studio Build Tools 2022
+installed. Additionally, you need [cmake](https://cmake.org/), which can be
+installed for example using [scoop](https://scoop.sh/) with
+`scoop install cmake`.
+
+#### Building TagLib (MSVC)
+
+You can build and install the dependencies
+[utf8cpp](https://github.com/nemtrif/utfcpp) and optionally
+[zlib](https://www.zlib.net/) and
+[CppUnit](https://wiki.documentfoundation.org/Cppunit) yourself, but it is
+probably easier using a package manager such as [vcpkg](https://vcpkg.io/),
+which can be installed using `scoop install vcpkg` and then install the
+dependencies using `vcpkg install utfcpp zlib cppunit`.
+
+Now you can build TagLib from PowerShell.
+
+```
+# Adapt these environment variables to your directories
+$env:TAGLIB_SRC_DIR = "${env:HOMEDRIVE}${env:HOMEPATH}/projects/taglib/src/taglib"
+$env:TAGLIB_DST_DIR = "${env:HOMEDRIVE}${env:HOMEPATH}/projects/taglib/src/msvs_vcpkg_build"
+cd $env:TAGLIB_SRC_DIR
+cmake -B $env:TAGLIB_DST_DIR -DBUILD_SHARED_LIBS=ON -DVISIBILITY_HIDDEN=ON `
+  -DBUILD_TESTING=ON -DBUILD_EXAMPLES=ON -DBUILD_BINDINGS=ON `
+  -DCMAKE_BUILD_TYPE=Release `
+  -DCMAKE_TOOLCHAIN_FILE="$env:VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake" `
+  -G "Visual Studio 17 2022"
+cmake --build $env:TAGLIB_DST_DIR --config Release
+
+# Add directories containing DLL dependencies to path
+$env:Path += -join(";$env:TAGLIB_DST_DIR\taglib\Release;",
+"$env:TAGLIB_DST_DIR\bindings\c\Release;",
+"$env:VCPKG_ROOT\packages\cppunit_x64-windows\bin;",
+"$env:VCPKG_ROOT\packages\utfcpp_x64-windows\bin;",
+"$env:VCPKG_ROOT\packages\zlib_x64-windows\bin")
+cmake --build $env:TAGLIB_DST_DIR --config Release --target check
+
+# Install to \pkg folder on current drive
+cmake --install $env:TAGLIB_DST_DIR --config Release --prefix /pkg --strip
+
+# Static library
+$env:TAGLIB_DST_DIR = "C:/Users/fle/projects/taglib/src/msvs_vcpkg_static_build"
+cmake -B $env:TAGLIB_DST_DIR -DBUILD_SHARED_LIBS=OFF -DVISIBILITY_HIDDEN=ON `
+  -DBUILD_TESTING=ON -DBUILD_EXAMPLES=ON -DBUILD_BINDINGS=ON `
+  -DCMAKE_BUILD_TYPE=Release `
+  -DCMAKE_TOOLCHAIN_FILE="$env:VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake" `
+  -G "Visual Studio 17 2022"
+cmake --build $env:TAGLIB_DST_DIR --config Release
+
+cmake --build $env:TAGLIB_DST_DIR --config Release --target check
+
+# Install to \pkg_static folder on current drive
+cmake --install $env:TAGLIB_DST_DIR --config Release --prefix /pkg_static --strip
+```
+
+Including `ENABLE_STATIC_RUNTIME=ON` indicates you want TagLib built using the
+static runtime library, rather than the DLL form of the runtime.
+
+#### Building a Project Using TagLib (MSVC)
+
+As an example for an external application using TagLib, we create a folder
+taglib-client and copy the file tagreader.cpp from the examples folder
+of the TagLib sources into it. We then add this simple CMakeLists.txt.
+
+```
+cmake_minimum_required(VERSION 3.5.0)
+project(taglib-client)
+set(CMAKE_CXX_STANDARD 17)
+find_package(ZLIB)
+find_package(TagLib 2.0.0 REQUIRED)
+add_executable(tagreader tagreader.cpp)
+target_link_libraries(tagreader TagLib::tag)
+```
+
+To build into a folder build inside this directory, just run
+
+```
+# Set this to the path where TagLib is installed
+$env:TAGLIB_PREFIX = "/pkg"
+cmake -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="$env:TAGLIB_PREFIX" `
+  -DCMAKE_TOOLCHAIN_FILE="$env:VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake" `
+  -G "Visual Studio 17 2022"
+cmake --build build --config Release
+
+# Add directories containing DLL dependencies to path
+$env:Path += ";$env:TAGLIB_PREFIX\bin;$env:VCPKG_ROOT\packages\zlib_x64-windows\bin"
+build\Release\tagreader /path/to/audio-file
+```
+
+To use the C-bindings with tagreader_c.c, you can change the last two lines in
+CMakeLists.txt to
+
+```
+add_executable(tagreader_c tagreader_c.c)
+target_link_libraries(tagreader_c TagLib::tag_c)
+```
+
+If you link against a static TagLib, you have to adapt the installation path
+(e.g. "/pkg_static") and add the following line to CMakeLists.txt
+
+```
+target_compile_definitions(tagreader_c PRIVATE TAGLIB_STATIC)
+```
+
+### Using MSYS2
+
+#### Building TagLib (MSYS2)
+
+To build TagLib using Clang from MSYS, install [msys2](https://www.msys2.org/),
+then start the MSYS CLANG64 shell and install the dependencies as they are
+specified in the [MSYS recipe for TagLib](
+https://packages.msys2.org/package/mingw-w64-clang-x86_64-taglib?repo=clang64).
+
+```
+pacman -Suy
+pacman -S mingw-w64-clang-x86_64-gcc-libs mingw-w64-clang-x86_64-zlib \
+  mingw-w64-clang-x86_64-cc mingw-w64-clang-x86_64-cmake \
+  mingw-w64-clang-x86_64-cppunit mingw-w64-clang-x86_64-ninja
+```
+
+Then you can build TagLib from the MSYS CLANG64 Bash.
+
+```
+# Adapt these environment variables to your directories
+TAGLIB_SRC_DIR=$HOME/projects/taglib/src/taglib
+TAGLIB_DST_DIR=$HOME/projects/taglib/src/msys_build
+cd $TAGLIB_SRC_DIR
+cmake -B $TAGLIB_DST_DIR -DBUILD_SHARED_LIBS=ON -DVISIBILITY_HIDDEN=ON \
+  -DBUILD_TESTING=ON -DBUILD_EXAMPLES=ON -DBUILD_BINDINGS=ON \
+  -DCMAKE_BUILD_TYPE=Release -G Ninja
+cmake --build $TAGLIB_DST_DIR --config Release
+
+PATH=$PATH:/clang64/bin:$TAGLIB_DST_DIR/taglib:$TAGLIB_DST_DIR/bindings/c \
+  cmake --build $TAGLIB_DST_DIR --config Release --target check
+
+# Install to /pkg_msys folder inside MSYS root (e.g. C:/msys64/pkg_msys/)
+cmake --install $TAGLIB_DST_DIR --config Release --prefix /pkg_msys --strip
+```
+
+#### Building a Project Using TagLib (MSYS2)
+
+As an example for an external application using TagLib, we create a folder
+taglib-client and copy the file tagreader.cpp from the examples folder
+of the TagLib sources into it. We then add this simple CMakeLists.txt.
+
+```
+cmake_minimum_required(VERSION 3.5.0)
+project(taglib-client)
+set(CMAKE_CXX_STANDARD 17)
+find_package(ZLIB)
+find_package(TagLib 2.0.0 REQUIRED)
+add_executable(tagreader tagreader.cpp)
+target_link_libraries(tagreader TagLib::tag)
+```
+
+To build into a folder build_msys inside this directory, just run
+
+```
+# Set this to the path where TagLib is installed
+TAGLIB_PREFIX=/pkg_msys
+cmake -B build_msys -DCMAKE_BUILD_TYPE=Release \
+  -DCMAKE_INSTALL_PREFIX=$TAGLIB_PREFIX -G Ninja
+cmake --build build_msys --config Release
+
+PATH=$PATH:$TAGLIB_PREFIX/bin
+  build_msys/tagreader /path/to/audio-file
+```
+
+To use the C-bindings with tagreader_c.c, you can change the last two lines in
+CMakeLists.txt to
+
+```
+add_executable(tagreader_c tagreader_c.c)
+target_link_libraries(tagreader_c TagLib::tag_c)
+```
+
+### Using MinGW
+
+The instructions for MSYS2 can also be used to build with MinGW. You could use
+Git Bash together with the MinGW provided by Qt.
+
+```
+# Adapt these environment variables to your directories
+PATH=$PATH:/c/Qt/Tools/mingw1120_64/bin
+TAGLIB_SRC_DIR=$HOME/projects/taglib/src/taglib
+TAGLIB_DST_DIR=$HOME/projects/taglib/src/mingw_build
+cd $TAGLIB_SRC_DIR
+cmake -B $TAGLIB_DST_DIR -DBUILD_SHARED_LIBS=ON -DVISIBILITY_HIDDEN=ON \
+  -DBUILD_EXAMPLES=ON -DBUILD_BINDINGS=ON -DWITH_ZLIB=OFF \
+  -DCMAKE_BUILD_TYPE=Release -G 'MinGW Makefiles'
+cmake --build $TAGLIB_DST_DIR --config Release
+
+PATH=$PATH:$TAGLIB_DST_DIR/taglib \
+  $TAGLIB_DST_DIR/examples/tagreader /path/to/audio-file
+
+# Install to C:\pkg_mingw
+cmake --install $TAGLIB_DST_DIR --config Release --prefix /c/pkg_mingw --strip
+```
+
+The installed package can then be used by other projects.
+
+```
+TAGLIB_PREFIX=/c/pkg_mingw
+cmake -B build_mingw -DCMAKE_BUILD_TYPE=Release \
+  -DCMAKE_INSTALL_PREFIX=$TAGLIB_PREFIX -G 'MinGW Makefiles'
+cmake --build build_mingw --config Release
+
+PATH=$PATH:$TAGLIB_PREFIX/bin
+  build_mingw/tagreader /path/to/audio-file
+```
+
+## Android
+
+### Using vcpkg
+
+The bash script below can be used to build TagLib for Android using vcpkg.
+It must be started in the parent folder of the taglib source folder and will
+build in a folder _android_build_ and install into _android_pkg_.
+The package and the unit tests are then transferred to an Android device
+and the unit tests are run on the device.
+
+Note that `TESTS_TMPDIR` is set because there is no system-wide temporary folder
+on Android. `TESTS_DIR` is set to run the tests on the target.
+
+```
+# You may have to adapt the NDK and vcpkg paths and the ABI/triplet.
+
+export ANDROID_NDK_HOME=$HOME/Development/android-sdk/ndk/23.1.7779620
+export VCPKG_ROOT=$HOME/Development/vcpkg

+### TagLib Audio Metadata Library
+
+https://taglib.org/
+
+TagLib is a library for reading and editing the metadata of several
+popular audio formats. Currently, it supports various metadata containers such
