[Kalzium] build failure

[Benoit Jacob]

Hello,

I get this when building kalzium:

[ 48%] Generating labelengine.moc
[ 48%] Generating ui_orbitalsettingswidget.h
/home/gaston/cuisine/trunk/kdeedu/kalzium/libavogadro-kalzium/src/engines/labelengine.h:103:
Error: Undefined interface
make[2]: *** [kalzium/libavogadro-kalzium/src/engines/labelengine.moc] Error 1
make[1]: *** [kalzium/libavogadro-kalzium/src/engines/CMakeFiles/labelengine.dir/all]
Error 2
make[1]: *** Waiting for unfinished jobs....
[ 48%] Generating orbitalengine.moc
/home/gaston/cuisine/trunk/kdeedu/kalzium/libavogadro-kalzium/src/engines/orbitalengine.h:150:Error:
Undefined interface
make[2]: *** [kalzium/libavogadro-kalzium/src/engines/orbitalengine.moc] Error 1
make[1]: *** [kalzium/libavogadro-kalzium/src/engines/CMakeFiles/orbitalengine.dir/all]
Error 2

I really don't understand what makes MOC fail to find the interface,
all seems well, the interface is defined in <avogadro/engine.h> which
is included by the file in question and is in cmake's include path (i
checked).

Cheers,
Benoit
