Pcap functions undefined reference

Question

I'm trying to add pcap functions into my C++ project in Clion on linux.

My h file contains:

#include <pcap/pcap.h>

And the CMAKE file was updated as well.

Instead of using the next command:

if (NOT MSVC)
    target_link_libraries(${TARGET} pthread)
endif()

it is now:

if (NOT MSVC)
    target_link_libraries(${TARGET} pthread pcap)
endif()

still getting the next errors:

undefined reference to "pcap_open_dead"
undefined reference to "pcap_dump_open"
undefined reference to "pcap_dump_close"
undefined reference to "pcap_close"

Anyone knows how to solve it?

Thanks

Can you compile in [`VERBOSE`](https://stackoverflow.com/q/4808303/7582247) mode and show the output you get? — Ted Lyngmo, Jan 25 '21 at 07:58
And please tell us where the pcap library is actually located... — U. W., Jan 25 '21 at 08:01

Thanks for the help!

After using the VERBOSE flag I was able to see the problem.

I added the pcap flag in another CMAKE file and now it works :)
