Support dynamic version for dev and releases.

[ccoulombe]

When installing from HEAD, this would allow one to have traceable reproducibility.
A local wheel built today from a fresh clone, would be tagged alphafold3-3.0.2.dev113+gebfe70a27.d20260206-cp313-cp313-linux_x86_64.whl.

The version is incremented from the current tag.
A dev release suffix which show that 113 commits have been made since.
A local version +gebfe70a27.d20260206 which means :

• gebfe70a27 (g+short commit)
• d20260206 (d+date)

Hence it is easy to know which build/commit a user used as it is described in the file name.

Wouldn't the CMake part need to be updated as well?

[ccoulombe]

Which cmake part more precisely are you referring to?

Sorry for the late reply. Will this work correctly with this line in CMakeLists.txt:

project(
  "${SKBUILD_PROJECT_NAME}"
  LANGUAGES CXX
  VERSION "${SKBUILD_PROJECT_VERSION}")

The ${SKBUILD_PROJECT_VERSION} variable in particular.

With the changes from this PR, I was able to build ebfe70a27a6a1ad18c77664191c5f7fa486ebee9 of AF3.

  Created wheel for alphafold3: filename=alphafold3-3.0.2.dev113+gebfe70a27.d20260402-cp313-cp313-linux_x86_64.whl size=242965375 sha256=221d6b8d0464d5018a373e5dd1aab767cb3f0eb75883e0e74024b2f23cdef61c

And adding some print status from CMake:

  -- Detecting CXX compile features - done
  -- >>> SKBUILD_PROJECT_VERSION = 3.0.2
  -- >>> PROJECT_VERSION = 3.0.2

Thus, I'd say yes. Esp. since it is scikit-build-core that manage the version via

metadata.version.provider = "scikit_build_core.metadata.setuptools_scm"

From the documentation,

If you need to set the CMake project version without scikit-build-core (which provides ${SKBUILD_PROJECT_VERSION})

we could infer that it manages the variable SKBUILD_PROJECT_VERSION correctly.
