I think the issue of tweaking the build system and its implicit inputs
must be addressed separately. We first need a good API to do that.
When we have it, it’ll be nice and easy to drive it via package
parameters. :-)
Currently each build system has ad-hoc keyword parameters to customize
its implicit inputs: #:python for ‘python-build-system’, #:cmake for
‘cmake-build-system’, #:implicit-inputs? for ‘gnu-build-system’, etc.
For each of them, it would be quite easy to provide a procedure that
takes a list of implicit inputs and returns a <build-system>. It may
not be all that convenient, and perhaps a bit too ad-hoc still.
Another option would be to make implicit inputs a field of
<build-system>.
Needs more thought!
Ludo’.
