At least on windows we do not re-run datatoc when the .glsl files change. To test is simple, just change edit_mesh_overlay_common_lib.glsl remove lines, write plain text, ..., now rebuild and go in edit mode with the default cube. I also had to remove the entry in gpu/CMakeLists.txt for gpu_shader_material.glsl since this was being tracked directly, as well as running data_to_c_simple (otherwise CMake raises an error for duplicated entries). We probably want to do the same for the other datatoc functions. Reviewers: LazyDodo, brecht Differential Revision: https://developer.blender.org/D3803
