* The GNUInstallDirs module is more idiomatic and supported by
  Kitware upstream, whereas the current directories are not
  standardised across CMake-using packages. Using CMake native

* Require CMake 3.1.0 at a minimum
* Fixed lower/UPPERcase format for function/macro calls
* Fixed indents by replacing tabs with 4 spaces
