If you want a copy of mlpack without MPL code included, you will need to

 * Remove all of the above-listed files.
 * Remove the above-listed files from CMakeLists.txt.
 * Remove the above-listed files from arma_extend.hpp.
 * Modify the root CMakeLists.txt to require a sufficiently new version of
 * Armadillo that none of the above backports are required, by changing the line
   "find_package(Armadillo x.yyy.z REQUIRED)" to reference a sufficiently new
   version instead of x.yyy.z.
