I need to do the equivalent of "cd /usr/src/cddl/usr.sbin/dtrace; make

cd /usr/src

make buildenv
make all install
but it pulls in libraries from the base system, which differ slightly from
those in the source tree.
The above will create the right /mumble hierarchy, and will pull the libraries
from the build rather than the local system.
How can I force it to use /mumble2/include and /mumble2/lib instead of / ?
I can pre-populate /mumble2 using "make buildworld", "make libraries", and "make
includes" but
I need to be able to do selective builds of just subdirectories after that.. I haven't
spotted the right way of forcing the use of the "--system_root /mumble2" option
in the compiles.
I know we do it in 'buildworld' is there a more generic way?
I have been looking in the .mk files but I haven't spotted it so far.
You’re asking for some serious split-brain action. chroot builds are likely
your best option. There’s no easy way to force this, although you might get
some milage out of WMAKEENV options, but I think we bake most of the where to
look for things options into the binaries. One crazy option would be to set
CC=“cc —sysroot /mumble” but I’m sure there be dragons there…
Good luck with this crazy, never have we supported it very well, option :)

Actually the hooks are in place to do this stuff. Instead of make
buildenv to get an interactive shell you can do something like
BLDENV=`${MAKE} buildenvvars`
chroot buildchroot/ "env -i $${BLDENV} cd /usr/src/somewhere && \
make all install"

Is there a way to specify a different toolchain destination? i.e. not
/usr/obj/usr/src/tmp ?
