I guess it's my own fault for not learning how to write CMake

I thought:
make NDEBUG=1 DEVELOPER=1 vcxproj
was invented for this use case?

There is something fun with that *cross*
Is cmake able to cross-compile cmake by cmake now?

OK, that's fine if it works for you.
Please don't drop support for autoconf and Makefile, though.

Debian Buster (current stable) ships v3.13.4, I think I don't need to
mention old-stable of Debian (Stretch or Jessie).

Right now, we should --with-zlib=/path/to/zlib/root

I wish I could verify this.
