"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
