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. A pkg-config file is provided to link
the library as an external dependency.
In addition to the features already provided in its CMake alternative,
this Makefile supports the construction of static libraries and provides
an uninstall target. In any case, the main motivation behind its writing
is to use a good old well-established standard with simple features,
available on all UNIX systems, thus simplifying its portability and
support while being much lighter.
