if I change CMakeLists.txt line 234 if(PLATFORM MATCHES "mac") to if (${CMAKE_SYSTEM_NAME} MATCHES "Darwin") this error will be solved.

But i don't know how to change others like where:

    if(PLATFORM STREQUAL "mac32")
        target_link_libraries(test_server xquic  -lm ${CMAKE_CURRENT_SOURCE_DIR}/../libevent32/lib/libevent.dylib)
        target_link_libraries(test_client xquic  -lm ${CMAKE_CURRENT_SOURCE_DIR}/../libevent32/lib/libevent.dylib)
        target_link_libraries(demo_server xquic  -lm ${CMAKE_CURRENT_SOURCE_DIR}/../libevent32/lib/libevent.dylib)
        target_link_libraries(demo_client xquic  -lm ${CMAKE_CURRENT_SOURCE_DIR}/../libevent32/lib/libevent.dylib)
    elseif(PLATFORM STREQUAL "mac")
        target_link_libraries(test_server xquic -lm -L/usr/local/lib -levent)
        target_link_libraries(test_client xquic -lm -L/usr/local/lib -levent)
        target_link_libraries(demo_server xquic -lm -L/usr/local/lib -levent)
        target_link_libraries(demo_client xquic -lm -L/usr/local/lib -levent)
    else()
        target_link_libraries(test_server xquic -levent -lm)
        target_link_libraries(test_client xquic -levent -lm)
        target_link_libraries(demo_server xquic -levent -lm)
        target_link_libraries(demo_client xquic -levent -lm)
    endif()

Hi, try to use the cmake variables -DPLATFORM=mac to build xquic on MacOS as mentioned in https://github.com/alibaba/xquic/blob/main/docs/Platforms.md#macos-release. #12 Problem resolved after add -DPLATFORM=mac flag.
