Due to changes in the build environment shader_builder wasn't able to compile on macOs. This patch reverts several recent changes to CMake files. *dbb2844ed9*94817f64b9*1b6cd937ffThe idea is that in the near future shader_builder will run on the buildbot as part of any regular build to ensure that changes to the CMake doesn't break shader_builder and we only detect it after a few days.
