can't find libpthread_nonshared.a

I am trying to build opencv from source and I inserted cmake instructions, then when I enter make command, it reaches 11% and then shows the following error

/usr/bin/ld: cannot find /usr/lib/libpthread_nonshared.a collect2: error: ld returned 1 exit status make[2]: * [modules/core/CMakeFiles/opencv_core.dir/build.make:1435: lib/libopencv_core.so.3.4.4] Error 1 make[1]: [CMakeFiles/Makefile2:2342: modules/core/CMakeFiles/opencv_core.dir/all] Error 2 make: ** [Makefile:163: all] Error 2 (base) [hassanalsamahi@D-Link build]$

please any help how to solve this problem?
