Install doesn't work on Manjaro Linux

[popeyeotaku]

Builds fine, but when I run install as sudo it gives the errors:

Installing Linux x86_64 mkdir: cannot create directory ‘/usr/lib/x86_64-linux-gnu’: Not a directory ./install: line 35: /usr/lib/x86_64-linux-gnu/cmake/Tilengine/tilengine-config.cmake: Not a directory mkdir: cannot create directory ‘/usr/lib/x86_64-linux-gnu’: Not a directory ./install: line 37: /usr/lib/x86_64-linux-gnu/pkgconfig/tilengine.pc: Not a directory chmod: cannot access '/usr/lib/x86_64-linux-gnu/libTilengine.so': Not a directory

Support for non-debian distros relate to generic issue #33
