Still getting libplacebo not found using pkg-config error #200

    @kevmitch I've adapted the scripts to support the `--wipe` functionality from your PR.

-lstd++ I added to both ffmpeg and mpv as they may both link against libplacebo, which may have glslang enabled.

I'd get an error from pkg-config when configuring ffmpeg without -lstd++:

/usr/lib64/gcc/x86_64-suse-linux/12/../../../../x86_64-suse-linux/bin/ld: /home/zeromind/src/github.com/zeromind/mpv-build/build_libs/lib/libplacebo.a(glsl_glslang.cc.o): undefined reference to symbol '_ZTVN10__cxxabiv117__class_type_infoE@@CXXABI_1.3'

I was still getting this error, everything builds fine after doing a sudo apt remove glslang-dev I assume libplacebo is built without it now and successfully picked up by ffmpeg's configure

Manually checking with pkg-config returned no error, maybe it is worth investigating more because the error is not what it seems.
