title: C++ CMake (add non-built files)
body: <p>I am using cmake to configure my project. I visualize project's files using qtcreator which read the CMakeLists.txt. 
  I have a few text files (non-code: config files, log, ..) and I would like to add them to my cmake project without (of course) compiling/linking them. Is it possible ?
  The main goal it to open them automatically in the tree of my project with qtcreator and edit them ...
  Thanks for help.</p>
