Can you try adding -lpthread to the compiler flags? That's what I found with 30 seconds of Googling.

[ghost]

Thank you!

[mkeeter]

Is this something that you could patch in a PR, so that it's fixed for other folks as well?

After adding
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread")
#include <util.h>
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wunused-parameter"
#pragma clang diagnostic ignored "-Wunknown-pragmas"
#pragma clang diagnostic ignored "-Wunused-variable"
#pragma clang diagnostic ignored "-Wunused-function"
#pragma clang diagnostic ignored "-Wdeprecated-register"
#pragma clang diagnostic ignored "-Wmissing-field-initializers"
#pragma clang diagnostic ignored "-Wunused-but-set-variable"
#pragma clang diagnostic ignored "-Wmissing-field-initializers"
#pragma GCC diagnostic ignored "-Wmaybe-uninitialized"
#pragma clang diagnostic pop

I am having the result like below
