Can't compile on Ubuntu

[sbash]

Main error is here: CMakeFiles/cmTC_9477e.dir/CheckFunctionExists.c.o` -o cmTC_9477e -lpthreads /usr/bin/ld: cannot find -lpthreads

find /lib -name "pthread" /lib/i386-linux-gnu/libpthread-2.23.so /lib/i386-linux-gnu/libpthread.so.0 /lib/x86_64-linux-gnu/libpthread-2.23.so /lib/x86_64-linux-gnu/libpthread.so.0

nm /lib/x86_64-linux-gnu/libpthread.so.0 | grep "pthread_create" 0000000000007990 t __pthread_create_2_1 0000000000007990 T pthread_create@@GLIBC_2.2.5

is the issue -lpthreads, not lpthread?
