BLD: Add CMake option to build Python bindings without rebuilding libz3 (redux) (#8088)
* Add CMake option to build only Python bindings without rebuilding libz3 Introduce Z3_BUILD_LIBZ3_CORE option (default ON) to control whether libz3 is built. When set to OFF with Z3_BUILD_PYTHON_BINDINGS=ON, only Python bindings are built using a pre-installed libz3 library. This is useful for package managers like conda-forge to avoid rebuilding libz3 for each Python version. Changes: - Add Z3_BUILD_LIBZ3_CORE option in src/CMakeLists.txt - When OFF, find and use pre-installed libz3 as imported target - Update Python bindings CMakeLists.txt to handle both built and imported libz3 - Add documentation in README-CMake.md with usage examples Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com> * Fix CMake export issues when building only Python bindings Conditionally export Z3_EXPORTED_TARGETS only when Z3_BUILD_LIBZ3_CORE=ON to avoid errors when building Python bindings without building libz3. Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com> * Disable executable and test builds when not building libz3 core When Z3_BUILD_LIBZ3_CORE=OFF, automatically disable Z3_BUILD_EXECUTABLE and Z3_BUILD_TEST_EXECUTABLES to avoid build/install errors. Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com> * only build src/ folder if Z3_BUILD_LIBZ3_CORE is TRUE * move z3 python bindings to main CMake * move more logic to main CMakeLists.txt * move Z3_API_HEADER_FILES_TO_SCAN to main CMakeLists.txt --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
