That's your opinion. And you are assuming that what you propose will not
require CMake (nor `make') knowledge for maintainance, something that I
In fact, as your proposed system deals with both build systems it acts
as a common denominator, thus restricting the evolution of them, as some
features that could be easy to implement on cmake but difficult on
`make' now must go through your scripts, which act as a deterrent.

This is unfair, bordering disinformation, I'll say. Most of those lines
are plain lists of file names and library dependency info. Then comes
support for user options, then platform tests. The actual amount of
cmake code is a tiny fraction of those 7k lines.
