[CMake] Trouble using QT_WRAP_* in out-of-source builds

[Sören Freudiger]

Hi Dave
we had have a similar problem.
because of this I first made a core solution to this and after that I
defined two macros

this will create the header, cpp and moc file whereever you want. don't
forget to put these files to the ADDITIONAL_CLEAN_FILES, then they will be
deleted at clean.

usage:
QT_WRAP_CPP3(/home/source/folder/MOC GENERATED_MOC_FILES
/home/source/folder/neddToBeMoced.h)

QT_WRAP_UI3(/home/source/folder/header 
            /home/source/folder/CPP 
		/home/source/folder/MOC
            GENERATED_HEADER_FILES
            GENERATED_CPP_FILES
            GENERATED_MOC_FILES       
            /home/source/folder/test1.ui /home/source/folder/test2.ui)

I think it's easy to understand hoe the macros are working.
You can fit them to your problem!

Betreff: [CMake] Trouble using QT_WRAP_* in out-of-source builds

My project uses Qt and I'm getting a problem with compilation of the uic
generated .h sources. These are created in the build tree but the include
paths aren't being set to reflect this so when, later in the build, the
header gets included in a source file it doesn't get found.

An in-source build works fine.

OS: MacOSX Tiger
CMake: version 2.3-20050831
