This adds
lbt_find_backing_library()
, which is a useful debuggingroutine to allow advanced users/package authors to query LBT to
determine which backing BLAS library will service a particular BLAS
call. It also exposes the "footgun API", which allows users to directly
set/get forwarding on a per-function basis. Because this has the
ability to generate truly bizarre setups, we do not advertise this
capability broadly (simply using
lbt_forward()
should be enough formost usecases) however it's nice to have wrapped.
