Install caffe system-wide

[vladfi1]

I'd like to use both caffe (C++) and pycaffe in some of my projects. I've managed to make all and even make runtest, but there doesn't appear to be any make install. I've seen some comments here and there about copying files, symlinking files, or adding directories to PYTHONPATH and the like, but these haven't worked for me. What is the right way to do this?

if you use debian or ubuntu, you may try to build deb packages by yourself.
see #2601
so manual management can be avoided.

I'd also like to see a proper install target. make distribute is the current solution, but it installs binaries to build/ instead of bin/ and the Python bindings are just dumped in python/.

IIRC, CMake just does the same thing as the raw Makefile build. We should let CMake do what it wants to do - install things to standard locations.

@cdluminate cleaning up the make install target would simplify the deb package creation scripts a bit.

A make install target for the Makefile and CMake sounds like a good idea if anybody wants to send the PR.

I'm fixing the cmake install stuff for the Debian packages.

GNUInstallDirs cmake module is used for Debian package.
To properly install the python module we need another cmake script finding the python module install path.
