What's the best way to set up Makefiles?

You're going to find this is a matter of opinion. Traditionally, GTK+
and GNOME projects have used GNU autotools for their build system. Many
are now moving to meson. Either way, I suggest you take some time and
learn one or both in order to make an informed decision about which
build system is best for you.

Meson is relatively new, and has most of its documentation on its
website[1]. GNU autotools has a vast online manual available[2],
however I recommend reading "Autotools: A Practition's Guide to to GNU
Autoconf, Automake, and Libtool"[3] to get a hands-on understanding of
the autotools suite.

2:, etc.

You could, of course, eschew all of those and use your own hand-
maintained Makefile. You'll find varying levels of opinion there too,
although you'll encounter some pretty compelling arguments against
maintaining your own hand-crafted Makefiles anywhere you look. In this
case, you could consider at least using pkg-config to find out whether
your required libraries are installed and where they are located on
your build host.

I'm actually working with Anjuta.
Anjuta is Makefile-based.

The problem is that if I change something I need to do a 'git pull',
which overwrites
the "pkg-config --includedir gtk+2" to be "pkg-config --includedir gtk+3".

So I'm thinking to just create an environment variable - something
like "USE_GTK3",
export it on the machine set for GTK3, then fix the for my project.
Then this will be kept independently of which version I have installed
on the system.

Or is there a better and simpler alternative? Maybe pkg-config has
something like
"set the current GTK+ version to be GTK+3"?

Thank you.

Is it feasible to define some environment variable and select GTK
version if it defined?

Or there is a better alternative?

Thank you.
