It gets kinda awkward when my Swift build, which uses distcc over 100 cpus for C++ compilation, tries to do 100 parallel swift compilations (not supported by distcc) on my poor local 4-core machine. I may have to resort to postprocessing the generated Ninja files if I can't modify CMake. -- -Dave -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.

They assign link rules and compile rules for that target to the named pool. Each pool can have a different size assigned in the global JOB_POOLS property.

We currently have no interface to assign custom commands or custom targets to any pool, simply because no one implemented such support. It would have to be a new optional argument to the add_custom_command and add_custom_target commands. -Brad -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.

[cmake-developers] How to use JOB_POOLS?
Hi all, I'm finding that the documentation for JOB_POOLS is... sparse, to say the least. I understand the principle at work, but it's really unclear how JOB_POOL_LINK and JOB_POOL_COMPILE are supposed to work when set per-target. When set globally, it's clear that JOB_POOL_COMPILE is supposed to affect “compilation” targets (which I presume means compilation of languages that CMake knows about?) while JOB_POOL_LINK is supposed to affect link targets (a little more constrained; I think CMake knows about most linkers) but what about custom targets? I have lots of those and their compilations can't be distributed with distcc. Can they be assigned to job pools? Can anyone explain this stuff? Thanks, Dave P.S. Someone should build up an example that illustrates how this all works. -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.

If you can create a merge request at gitlab.kitware.com, then that would be the best option. Not sure you can get an account there (that is able to create merge requests). Otherwise sending it here will probably work, too.
