Overriding glslang to 14.3 make cemu build again, see https://github.com/azuwis/nixpkgs/tree/push-szqvlxryoopy

The glslang issue is an easy fix without needing to downgrade the dependency.

According to glslang's README, the libraries have been consolidated into the main glslang library, but Cemu links the glslang::SPIRV target, which now provides an empty library. Seems to be a backwards-incompatible change and other things that use it should probably be checked.

You can patch src/Cafe/CMakeLists.txt to replace glslang::SPIRV with glslang::glslang and the package will build successfully.
