  cmake: move modules into the "cmake/" top level dir
  
  Our custom CMake module currently live in "cmake/Modules". As the
  "cmake/" directory doesn't contain anything except the "Modules"
  directory, it doesn't really make sense to have the additional
  intermediate directory. So let's instead move the modules one level up
  into the "cmake/" top level directory.
