[CMake] Help cmake First project

[Rodrigo Faccioli]

Thanks Chuck and Angeliki. Thanks your help.

However, unfortunatelly, I couldn't fix.

In [1] I show all my project. In src directory there is all .c files. In
include directory there is .h files.

The protpred-Gromacs-NSGA2.c is one of executable. The others are:
protpred-Gromacs-Dominance.c,
protpred-Gromacs-Front.c, protpred-Gromacs-MC_Metropolis.c,
protpred-Gromacs-Mono.c, protpred-Gromacs-Random_Algorithm.c.

All executable share the include directory.

In [2] contains my Makefile that I have already used in my project.
Therefore, I would like to build this make file using cmake. Furthermore, I
would compile in windows too. Because of this, I have studied cmake. My
doubt is how can I build CMakeList.txt.

I appreciate any help.
