main': CheckSymbolExists.c:(.text+0x1b): 对 pthread_create

如何解决main': CheckSymbolExists.c:(.text+0x1b): 对 pthread_create

我正在使用带有命令的 cmake 构建 Faunus 软件 -->

$cmake . -DENABLE_OPENMP=ON -DENABLE_PYTHON=ON -DCMAKE_INSTALL_PREFIX:PATH=/home/user/localInstall/tstFaunusInstOpenMP -DPYTHON_EXECUTABLE=/home/user/anaconda3/envs/faunus-env/bin/python3.6 -DPYTHON_INCLUDE_DIR=/home/user/anaconda3/envs/faunus-env/include/python3.6m -DPYTHON_LIBRARY=/home/user/anaconda3/envs/faunus-env/lib -DCMAKE_CXX_FLAGS_DEBUG="-pthread"

我收到构建错误，例如：

我从中可以理解的是，文件“CheckSymbolExists.c”的一部分需要pthread_create。我在 C 中编写了一个简单的代码并使用选项运行：gcc example.c -lm -pthread 并且它工作正常但是如果我在没有 -pthread 选项的情况下运行，我会遇到关于 pthread_create 的相同错误。有人可以帮忙吗。
