CMake: Fix Compiling Shader Builder on macOS

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
* 1b6cd937ff

The 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.
