There is no reason to check for libswscale: it's been included in FFmpeg since about 4 years (it was originally split out of the repo), a bit before the Libav fork. See http://ffmpeg.org/archive.html#svn_to_git Also note that not using pkg-config to locate the libraries and its dependency is broken by design and not supported by FFmpeg. The FFmpeg project, like a large number of other projects, supports the library linking and its flags through the deployed .pc files (since years). CMake "finder" should solely rely on this. All these hardcoded paths don't make much sense and will likely break. (Yes I'm aware pkg-config support in CMake is really bad). [...] Best Regards, -- Clément B.
