Just a note:
applications/gtk-qt-engine builds with the current CMakeLists.txt in the directory. But the file looks like a generic cmakelists pulled from a project other than Trinity. I don't think it matters from looking at the simplicity of the code. Without the Trinity check included, you do have to supply a complete set of cmake variables with path, pkgconfig, etc. included. I don't think it will cause problems later, but it is somewhat of an oddity to look in a CMakeLists.txt and not see Serghei's familiar Trinity header :)
The build produces the following package files:
02:06 supersff:~/arch/tnotes> cat flist/trinity-app-gtk-qt-engine-list.txt ------------------------------------------------------------ Package: trinity-app-gtk-qt-engine 1222892-1.0 ------------------------------------------------------------ /usr/ /usr/lib/ /usr/lib/gtk-2.0/ /usr/lib/gtk-2.0/2.10.0/ /usr/lib/gtk-2.0/2.10.0/engines/ /usr/lib/gtk-2.0/2.10.0/engines/libqtengine.so /usr/share/ /usr/share/themes/ /usr/share/themes/Qt/ /usr/share/themes/Qt/gtk-2.0/ /usr/share/themes/Qt/gtk-2.0/gtkrc
From what I can tell -- it looks complete. If you notice something missing, let me know.
