title: Installing additional files with CMake
body: <p>I am attempting to supply some "source" files with some executables. I was wondering if there was a way to copy these source files to the build directory (From the source directory) then to the install directory using CMake.</p>
  
  <p>My more specific goal here is to include OpenCL kernels that I write in their own *.cl files.</p>
  
  <p>Example:</p>
  
  <pre><code>mkdir build
  cd build
  cmake ..
  make
  </code></pre>
  
  <p>Now my directory should have an executable (standard CMake) and <code>some_opencl_kernel.cl</code> which I open in my executable.</p>
