[vtk-developers] Problems building with cmake 3.3

[Atri Bhattacharya]

Hi!
Congratulations and thanks for another exciting release of vtk!

I am a packager of vtk for openSUSE [1], and I find that vtk 7.1 fails
to build, e.g. on openSUSE 13.2 (hd5 1.8.13, cmake 3.0.2), openSUSE
Leap 42.1 (hdf5 1.8.15, cmake 3.3.2), but builds fine on openSUSE Leap
42.2 (hdf5 1.8.15, cmake 3.5.2) and later. The error I see on the older
systems is along the lines of:
```
[  245s] -- [1;4;34mConfiguring proj library:[0m 
[  245s] -- 
[  245s] -- PROJ_CORE_TARGET                         = vtkproj4 
[  245s] -- PROJ_CORE_TARGET_OUTPUT_NAME             = vtkproj4 
[  245s] -- PROJ_LIBRARIES                           = vtkproj4 
[  246s] CMake Error at CMake/NewCMake/FindHDF5.cmake:483
(find_program):
[  246s]   find_program does not support NAMES_PER_DIR
[  246s] Call Stack (most recent call first):
[  246s]   CMake/FindHDF5.cmake:7 (include)
[  246s]   CMake/vtkModuleMacros.cmake:858 (find_package)
[  246s]   ThirdParty/hdf5/CMakeLists.txt:1 (vtk_module_third_party)
```
Any way we could continue to provide vtk 7.1 for these older
installations, or should we simply stop upgrading vtk for these? Thanks
for any help, suggestions, etc.

Best wishes.

which, upon success, I will submit to the official pkgs, which are
