[cmake-developers] RFC: CMake precompiled header support and custom compiler based implementation

[Adam Strzelecki]

Okie, seems cmake_parse_arguments does not like option with optional value, so REUSE needs always parameter. Now on HEAD:

	target_precompiled_header(app lib1 lib2 src/prefix.h REUSE app)

Which is equal to:

	target_precompiled_header(app src/prefix.h)
	target_precompiled_header(lib1 src/prefix.h REUSE app)
	target_precompiled_header(lib2 src/prefix.h REUSE app)
