[CMake] Using absolute values in include_directories directive

[Felipe Sodre dos Santos]

Hi John, thanks for answering.

I'm actually porting a project from VC++ to be built using CMake tools, and thus I'm first "translating" the VCPROJ files into CMakeLists.txt files. I'll try what you said, but I still would like to know if there's a way to do what I was trying to do.

Thanks !

If you need this only for Qt. Why don't you use the proper Qt support in CMake?

FIND_PACKAGE(Qt4 REQUIRED)
INCLUDE(${QT_USE_FILE})

# Use the include path and library for Qt that is used by VTK.
INCLUDE_DIRECTORIES(
  ${QT_INCLUDE_DIR}
 )
