Comment (by jdemeyer):

 If you need to add flags like
 {{{
 #!diff
 +              library_dirs = gsl_library_dirs,
 +              include_dirs = gsl_include_dirs),
 }}}
 you must put them in the `.pxd` files, not in `module_list.py`. The reason
 is that there are a lot more extensions than the ones in `sage/gsl/*.pyx`
 which use the gsl library. If you add those dirs and includes to the gsl
 `.pxd` files, then all extensions using gsl will automatically have the
 correct flags added.

 This currently applies only to gsl, since all other libraries that you
 changed are listed directly in `module_list.py`.
