Replace CMake by POSIX make
The build procedure is now written in POSIX make, which the user can
configure via the config.mk file. The main motivation behind this
translation is to use a good old, well-established standard with simple
functionality, available on all UNIX systems, thus simplifying its
portability and support while being much lighter.
Dependencies are updated to ensure that the version used provides a pc
file.

# Star Gebhart Factor
The purpose of this C library is to numerically compute the [Gebhart
-factor](https://en.wikipedia.org/wiki/Gebhart_factor) between 3D primitives.
-The Gebhart factor *B(i,j)* between two arbitrary surfaces *i* and *j* is
-defined as the fraction of the radiative flux emitted by *i* that is absorbed
-by *j*. It is not equal to the [form
-factor](https://en.wikipedia.org/wiki/View_factor) between *i* and *j*, even
-tough the difference is subtle: the form factor is the fraction of the
-radiative flux emitted by *i*, in direction of *j* (which is not necessarily
-totally absorbed by *j*). In our case, Gebhart factors have been integrated
-over *j*, which means that we compute the fraction of the radiative flux
-emitted by *i* that is absorbed by all other surfaces. It is obviously not
-equal to one, since a fraction of the flux can be re-absorbed by *i* itself.
-
-Star-GF estimates Gebhart factors with the Monte-Carlo method: it consists in
-simulating the trajectory of energy bundles according to a relevant physical
-model. Emission, absorption and reflection processes are therefore taken into
-account, as well as spectral aspects (surface properties can be defined as a
-function of wavelength). Should scattering processes in semi-transparent media
-be taken into consideration, it would be possible (even if actually not
-implemented). The main advantage of this statistical method is the fact it
-provides a numerical accuracy over each result: the Monte-Carlo method is often

referred as a reference method. Also, the resulting algorithm is totally
-decoupled from the geometry: it will remain the same for every scene, no matter
-how much data is used for its description. This geometry is provided by the
-caller through a scene managed by the
-[Star-3D](https://gitlab.com/meso-star/star-gf.git) library.
-
-Gebhart factors may finally be used in order to compute the radiative flux
-absorbed by each surface, and subsequently the net radiative flux over each
-surface. The main advantage of Gebhart factors over form factors is
-the associated flexibility in terms of reflection properties: while form
-factors are computed with the implicit assumption that surfaces are diffuse
-reflectors, there is no such restriction in the case of Gebhart factors; any
-type of reflection can be used (totally or partially specular surfaces).
-
-## How to build
-
-Star-GF is compatible GNU/Linux 64-bits. It relies on
-[CMake](http://www.cmake.org) and the
-[RCMake](https://gitlab.com/vaplv/rcmake/) package to build. It also depends on
-the [RSys](https://gitlab.com/vaplv/rsys/),
-[Star-3D](https://gitlab.com/meso-star/star-3d/) and
-[Star-SP](https://gitlab.com/meso-star/star-sp/) libraries.
-
-First ensure that CMake is installed on your system. Then install the RCMake
-package as well as the aforementioned prerequisites. Finally generate the
-project from the `cmake/CMakeLists.txt` file by appending to the
-`CMAKE_PREFIX_PATH` variable the install directories of the previous
-dependencies. The resulting project can be edited, built, tested and installed
-as any CMake project (Refer to the [CMake
-documentation](https://cmake.org/documentation)
-for further informations on CMake).
