The latter for now.

No, the -A option is for when the underlying build system (e.g. VS IDE)
has declarative options to specify things like that.

The find_program command is used for some generators. I don't recall
if GHS does its own thing or not. One could add it to ENV{PATH} or
see the documentation of the find_program command for how it searches.

Try making it a cache entry:
set(CMAKE_MAKE_PROGRAM /path/to/gbuild CACHE FILEPATH "path to gbuild")
Note that toolchain files are meant to be produced locally and
hard-coded for a local machine, so such content is appropriate.
