Steps to reproduce (Include if Applicable)

I'm trying to integrate conan to my project that uses sdl2 and sdl2-mixer, here my conanfile.txt:

[requires]
sdl2/2.0.9@bincrafters/stable
sdl2_mixer/2.0.4@bincrafters/stable
libalsa/1.1.5@conan/stable

[generators]
cmake_find_package

After run conan install .. --settings arch=x86, cmake -G Ninja .. and ninja I got error

It seems sdl2_mixer/2.0.4@bincrafters/stable not fills sdl2_mixer_LIBRARY_LIST in generated Findsdl2_mixer.cmake.

@Croydon do you have an idea what might be wrong here?
