We're perverting CMake and Cygwin make to use a cross-compiler for z/OS (IBM
mainframe). We've beaten it mostly into submission, but are hitting an issue
with definitions being passed. Cygwin make seems to be passing them in the
format:
-Dvarname value
rather than:
-Dvarname=value
and the cross-compiler doesn't like that much. Some discussion with more
*IX-savvy friends suggests that the "blank" format is older, and is deprecated
due to ambiguity (does "-Dvarname abc.c xyz.c" mean "set varname to abc.c and
compile xyz.c", or "set varname to 1 and compile abc.c and xyz.c"?).
Is there a flag or other setting to change this behavior?
I spent a bunch of time searching for any discussion, but "make" is a pretty
generic term, I get tens of thousands of hits with anything I've tried (it
doesn't help that most search engines strip "-D" to just "D", and then probably
drop that...).
