Ninja

Ninja is a small build system with a focus on speed.
https://ninja-build.org/

See the manual or
doc/manual.asciidoc included in the distribution for background
and more details.

Binaries for Linux, Mac, and Windows are available at
GitHub.
Run ./ninja -h for Ninja help.

Installation is not necessary because the only required file is the
resulting ninja binary. However, to enable features like Bash
completion and Emacs and Vim editing modes, some files in misc/ must be
copied to appropriate locations.

If you're interested in making changes to Ninja, read
CONTRIBUTING.md first.

Building Ninja itself

You can either build Ninja via the custom generator script written in Python or
via CMake. For more details see
the wiki.

Python

./configure.py --bootstrap

This will generate the ninja binary and a build.ninja file you can now use
to build Ninja with itself.

CMake

cmake -Bbuild-cmake -H.
cmake --build build-cmake

The ninja binary will now be inside the build-cmake directory (you can
choose any other name you like).

To run the unit tests:

./build-cmake/ninja_test
