Ninja

Generates build.ninja files.

A build.ninja file is generated into the build tree. Use the ninja program to build the project through the all target and install the project through the install (or install/strip) target.

For each subdirectory sub/dir of the project, additional targets are generated:

sub/dir/all

New in version 3.6: Depends on all targets required by the subdirectory.

sub/dir/install

New in version 3.7: Runs the install step in the subdirectory, if any.

sub/dir/install/strip

New in version 3.7: Runs the install step in the subdirectory followed by a CMAKE_STRIP command, if any.

The CMAKE_STRIP variable will contain the platform’s strip utility, which removes symbols information from generated binaries.

sub/dir/test

New in version 3.7: Runs the test step in the subdirectory, if any.

sub/dir/package

New in version 3.7: Runs the package step in the subdirectory, if any.

Fortran Support

New in version 3.7.

The Ninja generator conditionally supports Fortran when the ninja tool is at least version 1.10 (which has the required features).

Swift Support

New in version 3.15.

The Swift support is experimental, not considered stable, and may change in future releases of CMake.
