# Try to find the WebP library
|
||||
#
|
||||
# This will define:
|
||||
#
|
||||
# WebP_FOUND - True if WebP is available
|
||||
# WebP_LIBRARIES - Link to these to use WebP
|
||||
# WebP_INCLUDE_DIRS - Include directory for WebP
|
||||
# WebP_DEFINITIONS - Compiler flags required to link against WebP
|
||||
#
|
||||
# In addition the following more fine grained variables will be defined:
|
||||
#
|
||||
# WebP_WebP_FOUND WebP_WebP_INCLUDE_DIR WebP_WebP_LIBRARY
|
||||
# WebP_Decoder_FOUND WebP_Decoder_INCLUDE_DIR WebP_Decoder_LIBRARY
|
||||
# WebP_DeMux_FOUND WebP_DeMux_INCLUDE_DIR WebP_DeMux_LIBRARY
|
||||
# WebP_Mux_FOUND WebP_Mux_INCLUDE_DIR WebP_Mux_LIBRARY
|
||||
#
|
||||
# Additionally, the following imported targets will be defined:
|
||||
#
|
||||
# WebP::WebP
|
||||
# WebP::Decoder
|
||||
# WebP::DeMux
|
||||
# WebP::Mux
|
||||
#
|
||||
# Note that the Decoder library provides a strict subset of the functionality
|
||||
# of the WebP library; it is therefore not included in WebP_LIBRARIES (unless
|
||||
# the WebP library is not found), and you should not link to both WebP::WebP
|
||||
# and WebP::Decoder.
