Markus Reitböck 68114945fa Part: use CMake to generate precompiled headers on all platforms
"Professional CMake" book suggest the following:

"Targets should build successfully with or without compiler support for precompiled headers. It
 should be considered an optimization, not a requirement. In particular, do not explicitly include a
 precompile header (e.g. stdafx.h) in the source code, let CMake force-include an automatically
 generated precompile header on the compiler command line instead. This is more portable across
 the major compilers and is likely to be easier to maintain. It will also avoid warnings being
 generated from certain code checking tools like iwyu (include what you use)."

Therefore, removed the "#include <PreCompiled.h>" from sources, also
there is no need for the "#ifdef _PreComp_" anymore
