More portable like cmake scripts.  It is one more thing you have
to get to build the system.   The question is exactly what are
the perl scripts doing, and if it can be done in a clean readable
way with cmake directly it would be the preferred way to go.

However, it is not a default installation on many systems.   It is nice
when you can avoid the Easter egg.  I want to build X, ok then first install
A B C D...   They have to install CMake, so if you can do the job in cmake
without much effort, then I would say it should be done that way.

CMake strives to support every feature...   And if there is something missing
we can add it.

It maybe worthwhile to examine the purpose of existing perl scripts and
see how hard it would be to replace them with cmake code.
