Build In Windows Error

[ftlong6666]

Hi I tried to build this code in windows but I have this error which failed to find pthread.h

./src/sal_metric.cpp(13): fatal error C1083: Cannot open include file: 'pthread.h': No such file or directory
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Community\\VC\\Tools\\MSVC\\14.23.28105\\bin\\HostX86\\x64\\cl.exe' failed with exit status 2

Then I tried to download the library here but I got another error here.

./pthreads.1\pthread.h(339): error C2011: 'timespec': 'struct' type redefinition
C:\Program Files (x86)\Windows Kits\10\include\10.0.18362.0\ucrt\time.h(39): note: see declaration of 'timespec'
./src/sal_metric.cpp(14): fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory
