Update of /cvsroot/CMake/CMake/Tests/Preprocess
In directory public:/mounts/ram/cvs-serv16504/Tests/Preprocess
Added Files:
CMakeLists.txt file_def.h preprocess.c preprocess.cxx
preprocess.h.in preprocess_vs6.cxx target_def.h
Log Message:
ENH: Create COMPILE_DEFINITIONS property for targets and source files. Create <config>_COMPILE_DEFINITIONS property as per-configuration version. Add Preprocess test to test the feature. Document limitations on Xcode and VS6 generators.
