Replace current install variables with GNUInstallDirs
* 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 mechanisms is better than reinventing the wheel, as it makes using the build system more uniform across the ecosystem * Use CMAKE_CXX_STANDARD to force C++11 * Require CMake 3.1.0 at a minimum * Fixed lower/UPPERcase format for function/macro calls * Fixed indents by replacing tabs with 4 spaces
