compilation commands:

cmake -DCMAKE_BUILD_TYPE=Release -DMIXERX_ENABLE_GPL=ON -DDOWNLOAD_AUDIO_CODECS_DEPENDENCY=ON -DAUDIO_CODECS_BUILD_LOCAL_SDL2=ON ..

make -j8

Hello!
Sorry for no reply, I missed up your post.
I have a question: which compiler tool chain you used? As a small note, old MinGW is not supported by SDL2, and you need MinGW-w64 tool chain to properly build the thing.
