Do we really need to go down the road of making hlsl a 'first-class' language to add support for additional compile flags?

Right now .hlsl files are written by
cmVisualStudio10TargetGenerator::WriteExtraSource
because they are (perhaps incorrectly) not classified as compiled sources. Look at use of GetObjectSources in cmVisualStudio10TargetGenerator::WriteAllSources for where compiled sources get handled. The OutputSourceSpecificFlags method handles source-specific COMPILE_FLAGS.
The reason .hlsl files are not classified as compiled sources is because HLSL is not a first-class language in CMake that one enables via enable_language(). This also prevents them from being handled by non-VS generators. If you are interested in working on making HLSL a first-class language I can help you get started.
