I do this for my Visual Studio builds with a macro.

Then its usage in a project named laGUI
SET( laGUI_SRCS

./src/VTK2dWidget.cpp
./src/laCentralWidget.cxx

./Include/laTableWidget.h
./Include/laPipelineWidget.h
./Include/la2DView.h
./Include/la3DView.h
)
#Add precompiled header support
LA_PCH_SUPPORT(laGUI)
Then externally create
laGUIPCH.cxx
laGUIPCH.h
in the same folder as the CMakeLists.txt file for the project.
