如何使pthread_create在Clion上编译

Question

我使用pthread创建了线程池。 当我尝试pthread_create时，得到以下信息：

[ 25%] Building C object CMakeFiles/ex4.dir/threadPool.c.o
[ 50%] Building C object CMakeFiles/ex4.dir/test.c.o
[ 75%] Linking C executable ex4
CMakeFiles/ex4.dir/threadPool.c.o: In function `tpCreate':
/home/user2/CLionProjects/ex4/threadPool.c:54: undefined reference to `pthread_create'
collect2: error: ld returned 1 exit status
CMakeFiles/ex4.dir/build.make:113: recipe for target 'ex4' failed
make[3]: *** [ex4] Error 1
CMakeFiles/Makefile2:72: recipe for target 'CMakeFiles/ex4.dir/all' failed
make[2]: *** [CMakeFiles/ex4.dir/all] Error 2

make[1]: *** [CMakeFiles/ex4.dir/rule] Error 2
Makefile:118: recipe for target 'ex4' failed
make: *** [ex4] Error 2

我试图添加SET（CMAKE_C_FLAGS -lpthread），但是没有用。 我尝试通过终端进行编译，但同样失败。 有什么建议吗？
