[mlpack] Can't configure build

[Александр Горбань]

Thank for prompt response,

I installed Armadillo into /usr (CMAKE_INSTALL_PREFIX=/usr) and did make
install (actually I used checkinstall to build debian package).

I found that armadillo installation didn't created symlinks, and only put
libarmadillo.so.2.4.2 into /usr/lib, so after I created symlink
libarmadillo.so -> libarmadillo.so.2.4.2 configuration and build were
successful.

Thanks for help.
