Thanks for explaining.

By the way, the patch of mine is just a quick fix to not break the FFmpeg's configuration
process when enabling glslang, `./configure --enable-libglslang`, while either libglslang
up to release 13.1.1 or since 14.0.0 is installed in the system.

Accepting only glslang version 14.0.0 and above (--enable-libglslang) will obsolete this
patch: stub flags/libraries "-lOSDependent -lHLSL -lOGLCompiler" may just be dropped.

If useful, this patch is trivial even to backport, I am currently applying it to v6.1.1.
