Separate Metrics into "load" and "build" domains. Provide a way to record two different sets of metrics. This will be useful for persistent mode, where the "load" metrics will stay the same on each invocation, while the "build" metrics will be reset and recomputed on each incremental build invocation. + Add a new "dependency scan" metric which measures the time it takes to traverse the build graph to determine which commands need to run, before building anything.

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 on 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.
You can either build Ninja via the custom generator script written in Python or via CMake. For more details see the wiki.
./configure.py --bootstrap
This will generate the ninja binary and a build.ninja file you can now use to build Ninja with itself.
cmake -Bbuild-cmake 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
