Add shader source file to IDE but NOT compile them with cpp files

[ychding11]

• use cmake to build source file
• inspect and edit shader code in IDE, but Not compiling them with cpp files.

one solution is to set them to header file only.

set_source_files_properties("src/shaders/depth.vert" PROPERTIES HEADER_FILE_ONLY ON)
set_source_files_properties("src/shaders/forwardplus.vert" PROPERTIES HEADER_FILE_ONLY ON)
set_source_files_properties("src/shaders/forwardplus.frag" PROPERTIES HEADER_FILE_ONLY ON)
set_source_files_properties("src/shaders/light_culling.comp.glsl" PROPERTIES HEADER_FILE_ONLY ON)
