Per the customizing Makefile email, I'd like to ask if a mechanism exists or
could be implemented to allow CMakeLists.txt files to define commands that
pass a CPU count to subcommands - e.g. something that allows the generators
to take a syntax along the lines of:
ADD_CUSTOM_TARGET(subbuild
COMMAND ${CMAKE_COMMAND} --build ${TARGET_DIR} -- -j${PARENT_CPUS}
)
and generate makefiles that will take "make JOBS=3 subbuild" and have cmake
in turn launch "make -j3" in the target directory - in other words,
${PARENT_CPUS} would be a cue for the backend generator to add logic to pass
down parallel make settings to the subbuild command. (Ideally -j3 could be
passed down, but it looks like make itself precludes that so some other
variable would have to be used at the top level.)
Any insight is appreciated - this one has got me pretty stumped as to the
"right way" to achieve this effect.
Thanks,
CY
