include-import-lib option to bundle Windows import libraries in wheels#3017Conversation
…s in wheels Add a new `include-import-lib` option (defaults to false) in `[tool.maturin]` that includes the Windows import library (.dll.lib for MSVC, .dll.a for MinGW) in the built wheel. This enables users who distribute shared libraries via wheels to allow other programs to link against them at compile time. The import library path is extracted directly from cargo's JSON build output (the extra filenames reported alongside the primary artifact), so no extra file copying to staging directories is needed. Supported for all binding types that produce cdylibs/dlls: cffi, uniffi, and pyo3. Closes PyO3#2289
