====================[ Build | AsyncLogger | Debug ]============================= /snap/clion/169/bin/cmake/linux/bin/cmake --build /home/dyy/CLionProjects/AsyncLogger/cmake-build-debug --target AsyncLogger -- -j 6 [ 50%] Linking CXX executable AsyncLogger /usr/bin/ld: CMakeFiles/AsyncLogger.dir/main.cpp.o: in function `std::thread::thread<void (&)(), , void>(void (&)())': /usr/include/c++/9/thread:126: undefined reference to `pthread_create' collect2: error: ld returned 1 exit status make[3]: *** [CMakeFiles/AsyncLogger.dir/build.make:93：AsyncLogger] 錯誤 1 make[2]: *** [CMakeFiles/Makefile2:83：CMakeFiles/AsyncLogger.dir/all] 錯誤 2 make[1]: *** [CMakeFiles/Makefile2:90：CMakeFiles/AsyncLogger.dir/rule] 錯誤 2 make: *** [Makefile:124：AsyncLogger] 錯誤 2

解決方法：
在CMakeLists.txt的最后加上：

find_package(Threads REQUIRED) target_link_libraries(AsyncLogger Threads::Threads) #這里AsyncLogger 是你的項目名稱

然后reload CMakeLists.txt，編譯成功。
原因：
編譯器沒有鏈接線程庫
