I build ParaView nightly with the same non system Qt, and OpenMPI. I set
a few variables in my ~/.bash_profile that help CMake find QT:

	QT423=/opt/qt-4.2.3
	PATH=$QT423/bin:$PATH
	export PATH
	CMAKE_LIBRARY_PATH=$QT423/lib:$CMAKE_LIBRARY_PATH
	export CMAKE_LIBRARY_PATH
	CMAKE_INCLUDE_PATH=$QT423/include:$CMAKE_INCLUDE_PATH
	export CMAKE_INCLUDE_PATH
	
I also set the CMake initial path with:
	CMAKE_C_FLAGS:STRING=-I/usr/include/openmpi/openmpi/
	CMAKE_CXX_FLAGS:STRING=-I/usr/include/openmpi/openmpi/
	PARAVIEW_USE_MPI:BOOL=ON
	MPI_INCLUDE_PATH:PATH=/usr/include/openmpi
	MPI_LIBRARY:FILEPATH=/usr/lib64/openmpi/libmpi_cxx.so;/usr/lib64/openmpi/libmpi.so
