Failure to find ffmpeg/libavcodec header files during compilation #1954
Description
Description
Linux build script fails to find libavcodec header files on Fedora 43 with ffmpeg-devel from rpmfusion.
Component: lib_ccx
File: src/lib_ccx/hardsubx.c and src/lib_ccx/hardsubx.h
Problem
Compilation of ccextractor fails on systems where ffmpeg header files exist under /usr/include/ffmpeg. The header files are installed, they're just in a weird location and the environment variables aren't fixing it.
Compilation command used:
cd linux
export ENABLE_FFMPEG=1 FFMPEG_DLL_PATH='/usr/lib64' FFMPEG_INCLUDE_DIR='/usr/include/ffmpeg' FFMPEG_PKG_CONFIG_PATH='/usr/lib64/pkgconfig' RUST_BACKTRACE=full
./build -hardsubx -system-libs
Error message:

error: failed to run custom build command for `ccx_rust v0.1.0 (/builddir/build/BUILD/ccextractor-0.96.4-build/ccextractor/src/rust)`
note: To improve backtraces for build dependencies, set the CARGO_PROFILE_RELEASE_BUILD_OVERRIDE_DEBUG=true environment variable to enable debug information generation.

Proposed Fix
I haven't figured out how to fix this.
Impact
This issue causes compilation to fail.
This has been an issue for years and there's still a comment in the header and c files that say "// TODO: Correct FFMpeg integration", but there was a similar issue a while back that got closed as "not planned". I have been attempting to fix this for a while but I have no idea what I'm doing, is there at least a good work-around if it's not going to be fixed?
