autoconf test for GNUstep libraries/frameworks

[David Ayers]

Hello,

I'm looking for the canonical autoconf test to determine whether a
GNUstep library/framework is installed.  Specifically I would like to
test for -gui and libGorm.  (Well actually I might need a test that also
checks for AppKit/InterfaceBuilder at one point in time but right now
-gui and libGrom would suffice).

I've been offered an implementation of an m4 file (see attachment) but
this currently would have to augmented with the -make functionality of
probing for those suffixes (_d/_p/?) which we still seem to generate for
debug and profiled libraries.

I would like to avoid replicating that -make logic in m4 so I'd really
welcome an alternative.

Cheers,
David
