The following user-settable values for CMake are supported:
- TESTS_DIR: Tests directory, is path to unit test data when 'data' is
appended. Can be used to run the unit tests on a target.
- TESTS_TMPDIR: Directory for temporary files created during unit tests,
system tmpdir is used if undefined. Has to be defined on systems
without global temporary directory.
BUILD_TESTING is default enabled, which is a good default anyway.
Move the CppUnit check to the root CMakeLists.txt, simpler and clearer.
BUILD_TESTS is obsolete.
The need for BUILD_SHARED_LIBS=OFF for testing is not clear, it works on Linux.
But I kept it in the instructions for now.
