[CMake] RE: Qt 4.0 support in CMake and VTK

[Moreland, Kenneth]

I did eventually figure that out.  I went back, downloaded the source and compiled with the -no-framework option.  Everything worked fine except that CMake automatically changed the library flags from the expected -lQtGui (and the like) to -framework QtGui.  So right now, CMake is not working well with Qt compiled with or without frameworks (as of the CMake checked out on August 24).

Hi,

This might be a totally unnecessary as you probably are aware of this  
- but just in case you are not I thought I would submit it.

When you do a default configure of Qt4 on a Mac it does a 'framework'  
build and and the Qt modules land up in
/usr/local/Trolltech/Qt-4.0.1/lib/QtXXXX.framework - the header files  
are actually in
QTXXXX.framework/Versions/Current/Headers and the actual library is  
QTXXXX.framework/Versions/Current/QTXXXX (with no extension)

There are symlinks to both the headers and the library in  
QTXXX.framework

If you pass -no-framework to configure then you get something that  
looks the same as the linux install and the headers are then in /usr/ 
local/Trolltech/Qt-4.0.1/include/QtXXXX

But although Trolltech provides a 'framework' build it seems that  
qmake -query is not aware of it.

Unfortunately Qt4 users on OSX could have either of these  
configurations - something that will make cmake's job more complicated.

I hope that was helpful and not something you already knew :)
