Ok, I have written a sample patch series (attached) that should make
debhelper support cmake with the ninja backend.
The chosen syntax is:
dh <target> --buildsystem=cmake+ninja
A review and some testing would be appreciated.
Thanks,
~Niels

Subject: [PATCH 1/2] Rewrite build system to support a "target build system"
Several of the build systems consists of a configure step that
generates a buildscript for another build tool. Notable examples
being "cmake" and "meson", which even supports multiple backend tools.
This change makes it natively possible for debhelper to support such
build systems with multiple backends.
Note that only build systems with multiple backends have been
rewritten.
