Examples:

Install to deafult directory (/usr/local)
$ $(basename $0)
$ cd _build; sudo make install

Do not include Python wrapper, build in local dir
$ MILK_PYTHON=\"OFF\" $(basename $0) \$PWD/local
$ cd _build; make install

Build type Debug (default: Release)
$ MILK_BUILD_TYPE=\"Debug\" $(basename $0)
$ cd _build; sudo make install

Use CUDA
$ MILK_CMAKE_OPT=\"-DUSE_CUDA=ON\" $(basename $0)
$ cd _build; sudo make install

### NOTES ###

Grab version and link to folder - if you switch versions regularly, don't forget to hack your way around:
$ sudo ln -s /usr/local/milk-<version> /usr/local/milk

If it's your first compilation EVER
Check you bashrc for
  export MILK_ROOT=${HOME}/src/milk  # point to source code directory. Edit as needed.
  export MILK_INSTALLDIR=/usr/local/milk
  export PATH=${PATH}:${MILK_INSTALLDIR}/bin
  export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:${MILK_INSTALLDIR}/lib/pkgconfig
