### Using qwt with qt_ros

I am trying to build a qt_ros package which uses a custom .ui file with a couple of qwt widgets. The standard qt_ros package builds and displays the original main window gui. When I replace the old .ui file with the one I want to use, I get the message qwt_dial.h: No such file or directory. I have confirmed that the files exist in usr/include/qwt-qt4. The only thing I can think of is maybe there should be lines including qwt in package.xml and/or CMakeLists.txt, or qwt should be installed elsewhere. Any help would be appreciated.

edit: Earlier I added the path to the widget library to ui_main_window.h which is generated with catkin_make. This allowed the file to be found. It was then giving me an error with slot and signal; those had to be changed to Q_SLOT and Q_SIGNAL. Currently I am getting a few undefined reference errors involving QwtCompass and QwtDial.
