Yes, we've got 5.5.4_alpha_pre3 available using the emulator already.
We just need the actual mapping for AC_ARG_WITH/AC_ARG_ENABLE settings,
so we can translate that into selections we make and the selections
available to end users.

If you use the standard CMake names, we'll pick them up directly from
there.

Can you please explicitly include notes like in the documentation you
prepare?
I think the main thing with the CMake migration document will be the
tristate (disabled/static/dynamic) selection of engines.
For reference only, here's the blocks of Gentoo's build code to convert
system+user selections into the configure arguments:
