And I will not apply it, because it does actually break some packages
because of ninja.

For example, compiler-rt complains with:

    ninja: error: dependency cycle: include/sanitizer/allocator_interface.h -> include/sanitizer/allocator_interface.h

So, maybe the package is broken and needs fixing, but it (supposedly)
builds OKi-ish with makefiles.

So, we need to assess how many of the cmake packages build fine with
ninja. If they are the vast majority, then we annonate those that don't
and change the default to use ninja. If however, the vast majority does
not work with ninja, then we keep the curremnt status quo, and annotate
those packages that do, like webktigtk or wpewebkit.

Also, please have a look at qt6: it is already using ninja, but like
webkitgtk and wpewebkit, is was special-coded. Could you please send
a follow-up patch that upgrades qt6 to use QT6_CMAKE_BACKEND?

Regards,
Yann E. MORIN.
