Comment (by cal@…):

 Instead of using

 {{{
 github.setup erincatto Box2D v2.3.1
 }}}

 and explicitly setting the `version` property, use

 {{{
 github.setup erincatto Box2D 2.3.1 v
 }}}

 which will automatically set the version number correctly.

 Additionally, `worksrcdir` is not supposed to be an absolute path.
 `worksrcpath` will be composed of `${workpath}/${worksrcdir}`, so you
 should use

 {{{
 worksrcdir Box2D-${version}/Box2D/
 }}}


 You should not have to set `cmake.build_dir`. The default should be fine.
