I don't know anything about cmake but...

the following files are installed in the root filesytem under

/ktnef
     ktnefattach.h
     ktnefdefs.h
     ktnefmessage.h
     ktnefparser.h
     ktnefproperty.h
     ktnefpropertyset.h
     ktnefwriter.h

Should they not be in /opt/trinity/lib

I could be missing something in cmake as I build the packages like this

   cmake ${_source}/${_module}/ \
     -DCMAKE_INSTALL_PREFIX=${trinity_prefix} \
     -DQTDIR=/opt/qt \
     -DQT_LIBRARY_DIRS=/opt/qt/lib \
     -DBUILD_ALL=ON
   make

Which gives me an error in my packaging tools
