Ah yes, I've been bitten by that before. It was maddening.

I don't think there is a reason not to. I'm guess it just hasn't been
a big enough issue to make the necessary changes to the CMakeLists.txt
files to ensure that the current directory is the first directory to
search. It should be possible to insert the current directory in the
front of the list in the 'vtk_module_library' function in
VTK/CMake/vtkModuleMacros.cmake where 'include_directories' is
called.include

Good point. I don't think the build bots start from a clean directory.
We probably haven't encountered this scenario since we started using
the buildbots, so I'm not sure how it would be handled.
