If you look at the ASDF manual C-h i m asdf, in chapter 4 you can find this:
There are a number of different techniques for setting yourself up
with ASDF, starting from easiest to the most complex:
* Put all of your systems in one of the standard locations,
subdirectories of
* '~/common-lisp/' or
* '~/.local/share/common-lisp/source/'.
If you install software there, you don't need further
configuration.(1)
That is to say ASDF searches these directiories for asdf systems by default. So just git-clone to ~/common-lisp and then do (require 'asdf) (asdf:load-system :{system name ie the name of the .asd file})
See the manual for further instruction.
