[Paraview] Problem building from source

[Tim Gallagher]

Hi,

I'm trying to build the code I just pulled on master:

> git branch
* master

> git describe
v3.14.1-2499-g16f07c1

I set VTK_USE_X to OFF:

> grep "USE_X" CMakeCache.txt
VTK_USE_X:BOOL=OFF

but it fails while building with:

Linking CXX shared library ../../../lib/libvtkGUISupportQt-pv3.14.so
CMakeFiles/vtkGUISupportQt.dir/QVTKWidget.cxx.o: In function `QVTKWidget::x11_setup_window()':

make[1]: *** [VTK/GUISupport/Qt/CMakeFiles/vtkGUISupportQt.dir/all] Error 2
make: *** [all] Error 2

Am I missing something? Why is VTK looking for X if I said not to use it? Does not using X imply QT shouldn't be turned on? If so, should that be enforced in CMake?

Thanks,

Tim
