Subject: [PATCH] Update CMake stuff to get it compiled in my up-to-date Debian
 system

- Changes regarding PCL:
  + PCL now requires C++14 compatibility
    => std=gnu++14 instead of previous std=gnu++0x
  + PCL uses some Boost components I needed to include as link deps

- Added GLVND as OpenGL preference
