CMake build

Complete the CMake build work. In particular CMake builds on Windows will need to be supported.

hello Spectrum enthusiast.
On first try on Linux Debian, I got this error:

efa@08i7-2500:~/c/The-Great-Escape-in-C$ build.sh

CMake Error at platform/generic/CMakeLists.txt:3 (add_executable):
  add_executable cannot create target "TheGreatEscape" because another target
  with the same name already exists.  The existing target is a static library
  created in source directory
  "/home/efa/c/The-Great-Escape-in-C/libraries/TheGreatEscape".  See
  documentation for policy CMP0002 for more details.

-- Configuring incomplete, errors occurred!
See also "/home/efa/c/The-Great-Escape-in-C/build/CMakeFiles/CMakeOutput.log".

I cannot identify what is the "existing target is a static library", there is only directories in /libraries

There's a clash between library and executable in that build. I've pushed a fix which renames the executable.
