It is better to read the INSTALL file when you are building a software. :-)
Or in the case of GIMP, If you build from git repository, then read
INSTALL.in instead. Everything is explained.

As you note yourself, libmypaint do not contain MyPaint brushes, which
is a problem. This is why mypaint-brushes is a separate package. It is
available in https://github.com/Jehan/mypaint-brushes
Install the branch v1.3.x and make sure that your PKG_CONFIG_PATH is
well set (once again, everything is explained in details in
INSTALL.in).

Yes these are installed with MyPaint, but this is a problem because:

(1) it makes MyPaint a defacto dependency to GIMP since we use
libmypaint (which is useless without brushes).
(2) there is no way to know where the brushes are but guessing. This
is what we were doing previously trying various common places (/usr,
/usr/local, etc.). But this is not an acceptable solution. We need to
know where each of our dependencies are actually installed with
certainty.

This is why we have a separate package which hopefully will be used
also soon by every project using libmypaint out there (instead of
duplicating these data everywhere! For instance, I read that it is
what OpenToonz is doing: they just ship MyPaint brushes which is not a
good idea).
