I'm trying to build FFmpeg (version 4.3.1) with --enable-libaom for Windows using MSYS and Microsoft Visual C++.
Configure script says: ERROR: aom >= 1.0.0 not found using pkg-config
But I have libaom (built it from sources) and paths to it are specified:
set INCLUDE=%INCLUDE%;%~dp0..\..\libaom-build\prebuilt\include;
set LIB=%LIB%;%~dp0..\..\libaom-build\prebuilt\windows\x64\lib;
This is how I call the configuration script:
./configure --prefix=$PWD/../../prebuilt/windows/x64 --toolchain=msvc --extra-cflags="-MD" --arch=x64 --disable-x86asm --disable-iconv --disable-network \
--enable-filter=stereo3d --enable-libmp3lame --enable-libaom --enable-libdav1d \
--extra-cflags="-I$PWD/../../../zlib-build/prebuilt/include -I$PWD/../../../libpng-build/prebuilt/include -I$PWD/../../../lame-build/prebuilt/include -I$PWD/../../../libaom-build/prebuilt/include -I$PWD/../../../libdav1d-build/prebuilt/include" \
--extra-ldflags="-L$PWD/../../../lame-build/prebuilt/windows/x64/lib -L$PWD/../../../libaom-build/prebuilt/windows/x64/lib -L$PWD/../../../libdav1d-build/prebuilt/windows/x64/lib"
Thanks to Gyan for pointing me out to ffbuild/config.log.
I've created aom.pc file and put it into /usr/lib/pkgconfig:
# libaom pkg-config.

This helped.
