Hm, under what circumstances would that be safe or a good idea?
The concerns that strike my mind are mainly around the hazard that
configure's choices could be inappropriate for a build with a
different SDK. Given that, though, wiring -isysroot into the
configure output doesn't seem all that insane.
It's possible that we could arrange things so that the generated
Makefile.global looks like
PG_SYSROOT =
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk
CPPFLAGS = -isysroot $(PG_SYSROOT)
instead of
CPPFLAGS = -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk
thus making it a bit simpler to override that path at build time.
But I'm not sure that that really moves the goalposts very far for you
in terms of ease-of-use, and anyway it might just be greasing the skids
to a non-working extension.
