: Unfortunately... CMake is a crap and I can't fix it. Well, honestly I
: don't want to fix it. But you're right: I can fix all these comments
: (athough I don't really want to). I have no idea how to express this in
: a more neutral way, so I propose the following:
: 1. s/CMake is a crap/there is no convenient way to make it in CMake/g.
: 2. Leave everything else unchanged.

Hmm, ok.

: 
: This is not only emotions. Such comments prevent one from unintentional
: refactoring of such fragile places with no failures and also from
: bothering the oldies with the questions kinda "dude, why is this done so
: badly". In other words, primarily I have left this for the history.
: 
: If you're OK, then I'll fix the way described above.

: I have thought about it for some time, and I have a strong rationale (at
: least for me) to not introducing such change: this doesn't work whether
: there are directories inside containing no tests. Furthermore, we're
: going to re-implement several C tests, so I would like to leave
: everything as it is (if you don't mind) and return to this place later.

Ok, if you plan to refactor it, because today it looks inconsistent a bit.
