source: code/trunk/cmake/BuildConfig.cmake @ 3594

Last change on this file since 3594 was 3330, checked in by rgrieder, 15 years ago

Added general PCH_ENABLE option in CMake to disable PCH with one simple option (use cmake -DPCH_ENABLE=FALSE when configuring).
Also moved all build-related options to BuildConfig and moved some code around there.
