This is not the right fix for your problems. It seems like there's a bug in avogadro's cmake-config file, possibly avogadro uses FindQt4 with the QT_USE_IMPORTED_TARGETS flag set and then it generates the config-file with an 'avogadro' target that has QtOpenGL in its link-interface. This causes a target to be created for that and exported. But kalzium does not call FindQt4 itself explicitly and hence does not set the QT_USE_IMPORTED_TARGETS. This causes cmake to not know that the QtOpenGL lib is an external lib.

In addition the cmake-config file from avogadro should put the imported target into a cmake variable and name it differently from the actual target in the avogadro build.
