i want to pass a cmake option to my port, what's is the best practice

[nocanstillbb]

in order to disable qt unit test, i want to pass a option to ignore unit test when vcpkg install . The way I think of is to read the json filed from a json file that put to vcpkg_root/port/myport in portfile.cmake, but I think there is a better way

If you always want to disable the test, you can use

vcpkg_cmake_configure(
    SOURCE_PATH "${SOURCE_PATH}"
    OPTIONS
        -DMY_FLAG_TO_DISABLE_TESTS=ON
)

If you have an option for it in the vcpkg.json file you can use

vcpkg_check_features(OUT_FEATURE_OPTIONS FEATURE_OPTIONS
   INVERTED_FEATURES
        my-enable-test-feature          MY_FLAG_TO_DISABLE_TESTS
)

vcpkg_cmake_configure(
    SOURCE_PATH "${SOURCE_PATH}"
    OPTIONS 
        ${FEATURE_OPTIONS}
)
