it is possible to send you a PM? I would like to make you a proposition thanks

You need to add pthread. You can see my cmake for the example, this contains the libraries youd need https://github.com/smasherprog/screen_capture_lite/blob/master/Example/CMakeLists.txt

[ROBERT-MCDOWELL]

but the list I provided shows libpthread installed no? /usr/lib64/libpthread* -rwxr-xr-x 1 root root 149360 Aug 29 10:19 /usr/lib64/libpthread-2.26.so -rw-r--r-- 1 root root 160520 Aug 29 10:19 /usr/lib64/libpthread.a -rw-r--r-- 1 root root 1732 Aug 29 10:19 /usr/lib64/libpthread_nonshared.a -rw-r--r-- 1 root root 222 Aug 29 10:17 /usr/lib64/libpthread.so lrwxrwxrwx 1 root root 18 Aug 29 10:17 /usr/lib64/libpthread.so.0 -> libpthread-2.26.so

I dont use fedora so i dont know. pthread is not being found though.
