# macOS-specific builder configurations and build commands

## Base configurations

.macos: &macos
    variables:
        GIT_CLONE_PATH: "$CI_BUILDS_DIR/cmake ci ext/$CI_CONCURRENT_ID"
        # TODO: Factor this out so that each job selects the Xcode version to
        # use so that different versions can be tested in a single pipeline.
        DEVELOPER_DIR: "/Applications/Xcode-11.5.app/Contents/Developer"

### Build and test

.macos_build: &macos_build
    extends: .macos

    variables:
        # Note that shell runners only support runners with a single
        # concurrency level. We can't use `$CI_CONCURRENCY_ID` because this may
        # change between the build and test stages which CMake doesn't support.
        # Even if we could, it could change if other runners on the machine
        # could run at the same time, so we drop it.
        GIT_CLONE_PATH: "$CI_BUILDS_DIR/cmake ci"

.macos_ninja: &macos_ninja
    extends: .macos_build

    variables:
        CMAKE_CONFIGURATION: macos_ninja
        CTEST_NO_WARNINGS_ALLOWED: 1

.macos_makefiles: &macos_makefiles
    extends: .macos_build

    variables:
        CMAKE_CONFIGURATION: macos_makefiles
        CTEST_NO_WARNINGS_ALLOWED: 1
        CMAKE_GENERATOR: "Unix Makefiles"

### External testing

.macos_xcode: &macos_xcode
    extends: .macos

    variables:
        CMAKE_CONFIGURATION: macos_xcode
        CMAKE_GENERATOR: Xcode
