History

PyCMake was created at SciPy 2014 in response to general difficulties building C++ and Fortran based Python extensions across platforms. It was renamed to “scikit-build” in 2016.

Known Issues

These issues are likely to be addressed in upcoming releases.

• Editable installs do not work with the latest versions of Setuptools (and had issues with older versions, too).

• Configuration scikit-build cares about _must_ be specified in setup() currently.

• The cache directory (_skbuild) may need to be deleted between builds in some cases (like rebuilding with a different Python interpreter).

We are also working on improving scikit-build, so there are some upcoming changes and deprecations:

• All deprecated setuptools/distutils features are also deprecated in scikit-build, like the test command, easy_install, etc.

• Older versions of CMake (<3.15) are not recommended; a future version will remove support for older CMake’s (along with providing a better mechanism for ensuring a proper CMake is available).

If you need any of these features, please open or find an issue explaining what and why you need something.
