[CMake] [Fwd: [Insight-users] Cmake - QT : moc problem]

[Hugo Gratama van Andel]

Dear CMake users,

I send you a message that appeared on the Itk-user list. I experienced 
the same error as described below. CMake 2.2.3 was not able to create 
the makefile correctly on a Linux system, while the previous version(s) 
of CMake were. Have the semantics of QT_WRAP_CPP changed?
thanks in advance,
Hugo

Hi everybody,

I'm currently updating a three months old segmentation
program and I'm very surprised that the compilation
process fails (althought it was succesfull three
months ago). It seems due to a problem with the
QT_WRAP_CPP command from the CMakeLists.txt file.

Actually I get an error like "No rule to build the
target « ATHENA_MOC_SRCS », which is necessary for «
moc_ATHENA_MOC_SRCS.cxx ». Stop." I am wondering: Is
there any change for the command QT_WRAP_CPP from the
version 2.0.6 to 2.2.3 of cmake? -> I did not have
this error three months ago...

When I change the line QT_WRAP_CPP(segment ATHENA_SRCS
ATHENA_MOC_SRCS) into QT_WRAP_CPP(segment Graphic.cxx
Graphic.h) I do not get the last error anymore but no
file "moc_Graphic.o" are builded, which is leading of
course to an executable linkage error...

I have copied the complete CMakeLists.txt file at the
end of this email.

Can you help me to solve this problem, please?
Thanks a lot for your help.

Happy New Year to you.
