[vtk-developers] getting rid of instantiators

John,

The only reason the IF(VTK_MAKE_INSTANTIATOR) tests were done before was
for backward compatability with CMake versions that didn't support the
command.  Now that a CMake release has the command in it, we don't need
the test anymore.

We can add another flag in the CMakeLists.txt files to turn instantiators
on/off, but I'm curious as to the reason you want to turn them off.  My
problem with making them optional is that it adds another possible way for
someone to build a version of VTK that doesn't work for their application.

I have an idea for a way to shrink the instantiator build times and create
only one instantiator source file per kit.  Would this be sufficient to
solve your problem, or is there another reason you want to turn them off?

Thanks,
-Brad
