Added first draft of CMakeLists.txt in preparation to configure cmake tool to work with the project
Working version of CMakeLists.txt. Project is currently compilable via cmake make (no install however) on my Ubuntu mashine. Windows and other linux distros (CentOS currently) are to be tested
Added build instructions to README
Modified FindGLM.cmake and README to make non-install glm usage easier. Compilation under CentOS distro is now possible, given that all dependencies are satisfied.
Small modification in README
