Yes, for the build directory. For the install directory, both will
export targets to the same file if VTK_INSTALL_NO_DEVELOPEMENT is OFF.
We could change that, if needed for the installed directory too, but I
am not convinced it's needed there.

We could make vtk_build_tools_target(..) macro add a dependency to a
custom vtkCompileTools target. That sounds reasonable. Alternatively,
it could add the target to a GLOBAL PROPERTY and then the top-level
cmake file could add a custom target that uses the value of this
global property and adds them as depedencies.  Hopefully, someone may
want to chime in which way is better.
