Removed cotire PCH Integrated native PCH by CMake with the same BUILD_USE_PCH flag Added new option to avoid extra files in 'build/include' folder and replace it by symlink Symlink creates link to the origin file, it has some benefits from debug and build side. The CMake parameter for symlink is 'BUILD_INCLUDE_SYMLINK'
