#1 libusbpp installed in wrong place: CMAKE_INSTALL_PREFIX is ignored.

[Drei Eck]

The installation directory of libusbpp is not the one of the rest of the project; CMAKE_INSTALL_PREFIX is ignored. I think it has to do with download of libusbpp after execution of cmake, when running make.

Please make libusbpp install in proper directories as specified when running cmake.

Even better, do not pull stuff from the internet when doing make ... please habe libusbpp as a dependency instead which is to be built and installed in an extra step, as an extra package.
