This change implements openal to use the sdl2 backend.
The main change in this is in openal-soft cmakeLists.txt it was not using our custom finders to find sdl2 for us before and so it had to be changed to a list append instead of a set. This needs to be remembered for future updates to openal
added libraries:
opus
flac
libsndfile
updated:
libvorbis
libogg
openal
- Everything works as expected for now. Bare in mind libsndfile needed the check for whether or not it could find the xiph libraries removed in order for this to work.
Fixed case sensitivity problem
Fixed clang compiler problem with having the class namespace used in an inline for the == operator
Tweaked some theme stuff to be more consistent.
Added initial test of no-pie for linux
test sidestep of getTexCoord in shadergen hlsl feature so we don't assert when getting the terrain's shaderstuffs(which uses float3 instead of normal float2)
