- Add GitHub workflow to build wheels on Linux (x86_64, aarch64), macOS (arm64), and Windows (x64) - Add cibuildwheel configuration in pyproject.toml - Use Development.Module instead of Development for manylinux compatibility - Configure OIDC trusted publishing for PyPI/TestPyPI
- macOS: Update MACOSX_DEPLOYMENT_TARGET to 15.0 (Homebrew libs require it) - Windows: Use forward slashes in vcpkg toolchain path for TOML compatibility - sdist: Use uvx with pyproject-build for proper build isolation

find_package(Python3 COMPONENTS Interpreter Development NumPy REQUIRED)to useDevelopment.Moduleinstead ofDevelopment.Why? The
Developmentcomponent requiresPython3_LIBRARIES(the full libpython), which is used for embedding Python in C++ applications. Manylinux containers don't include this library since it's not needed for building extension modules.Since simcoon builds a Python extension module (simmit.so), not an application that embeds Python,
Development.Moduleis the correct component. It only requires the Python headers, which are available in manylinux. This is also the recommended practice for pybind11 projects.Platforms
Python versions
