Cmake失败pthread.h

Question

There was once a bug related to cmake and pthread but it is now fixed。

我在Mac OS上使用cmake版本3.5.1。它先前编译过，但同时我安装，更改或更新了一些东西。我对cmake没有太多的了解。 cmake文件是由其他人编写的。

这是错误消息我得到：

-- Looking for pthread.h 
-- Looking for pthread.h - not found

我该如何解决这个问题？

感谢@Tsyvarev。 问题在于“-fopenmp”标志导致错误，因为编译器被设置为铛声。

从CMakeFiles/CMakeError.log

clang: error: unsupported option '-fopenmp' 

更改C++编译器g ++以及来自C编译器除去标志解决了这个问题。
