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. The make.sh script contains commands
that could be found directly in POSIX make, but which are placed here to
simplify writing the Makefile. Finally, 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 use of static libraries and provides an
uninstall target. It also enable compiler and linker options that
activate various hardening features aimed at increasing the security and
robustness of generated binaries. 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.
