#In ffmpeg code, old version use "#include <header.h>" and newer use "#include <libname/header.h>"
|
|
#In OSG ffmpeg plugin, we use "#include <header.h>" for compatibility with old version of ffmpeg
|
|
|
|
#We have to search the path which contain the header.h (usefull for old version)
|
|
#and search the path which contain the libname/header.h (usefull for new version)
|
|
|
|
#Then we need to include ${FFMPEG_libname_INCLUDE_DIRS} (in old version case, use by ffmpeg header and osg plugin code)
|
|
# (in new version case, use by ffmpeg header)
|
|
#and ${FFMPEG_libname_INCLUDE_DIRS/libname} (in new version case, use by osg plugin code)

# Macro to find header and lib directories
