To build:

    make;
    sudo make install;

To build in a specific directory outside of the source directory:

    make O=/path/to/build; sudo make O=/path/to/build

  Note that the path needs to exist before building.

To set the install path (the expected final location):

    make prefix=/usr; sudo make O=/path/to/build

To install in a directory not for the local system (for use to move
to another machine):

    make DESTDIR=/path/to/dest/ install

  Note, if you have write permission to the DESTDIR, then there is
  no reason to use sudo or switch to root.

  Note, DESTDIR must end with '/', otherwise the files will be appended
  to the path, which will most likely have unwanted results.
