fatal error C1083: Cannot open include file : 'pthread.h': No such file or directory

[hinhmd]

Hi,
I build with cmake on windows and VS 2015, and I got the error.
Here is the error log:

Determining if the include file pthread.h exists failed with the following output:

How can I fix it?

Sorry, I have never used MSVC. To me it sounds like it fails at this line: find_package(Threads REQUIRED) in CMakeLists.txt. I guess it could also be that your boost is build for pthreads instead of windows-threads? Hopefully, someone who knows Windows can answer this better than me:)
