Yes it is.
You could try this at the top of DemoUI/ CMakeLists.txt:
Qt Code: 
  1. FIND_PACKAGE(Qt4 COMPONENTS QtSvg QtScript REQUIRED)

Thank you very much! This worked to remove this particular error, but now I am getting the following error:
Qt Code: 
  1. Scanning dependencies of target DemoUI
  2. [ 58%] Building CXX object DemoUI/CMakeFiles/DemoUI.dir/GroupSelWidget.cpp.o
  3. In file included from /home/samjnaa/sr/_repos/hg/cornucopia-lib/DemoUI/GroupSelWidget.cpp:21:0:

But I have the Qt headers installed (indeed I'm sure it would have complained earlier if I had not):
Qt Code: 
  1. $ dpkg -S QWidget
  2. ...
  3. libqt4-dev: /usr/include/qt4/QtGui/QWidget
  4. ...

I am guessing that some CMake command is pointing to the wrong include directory or something. (Or perhaps the code needs to use "QtGui/" as in #include <QtGui/QWidget> but I'd prefer to hack the CMakeLists.txt if possible.) Please tell me what correction I have to do to get *this* working now?
