Ninja doesn't (yet) support the GNU Make jobserver out of the box,
but
there is a pull request adding that support[1]. Since that pull
request
(and its derived three-part pull requests) seem to be ignored by
upstream, kitware (creator/maintainer of cmake) has created a
fork[2]
only to carry the jobserver patches. Change the source uri to point
at
the kitware fork of ninja, and add two patches from the original
pull
request to also support the new-style fifo jobserver feature.
Note that the kitware fork of ninja is also used by buildroot[3].

support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+GNU make 4.4 introduced a new jobserver style "fifo" for POSIX
systems
+which passes a named pipe down to the clients.
+
+- update auth parser to recognize "fifo:<name>" format
+- open named pipe for reading and writing
+- make sure the file descriptors are closed in the destructor
+- add 2 tests that aren't compiled for WIN32
