Write a POSIX Makefile to replace CMake
The build procedure is written in POSIX make, which the user can
configure via the config.mk file.
In addition to the features already offered by its CMake counterpart,
this Makefile allows the programmer to specify static libraries as the
preferred type of libraries during the linking process. It also provides
an uninstallation target. In any case, the main reason for writing it is
to use a classic, well-established standard with simple features
available on all UNIX systems, which simplifies portability and support
while being much lighter.
Note that currently, test execution is still not automated in POSIX
make, unlike its CMake alternative.
