Undefined reference to curl libraries when trying to build kcov

[shailpatels]

Hi, I tried building kcov from the latest release and also from master but both times kcov failed to build due to linker errors. I'm building on Debian 12 and the triplet is x86_64-linux-gnu. The issue might be the same https://github.com/SimonKagstrom/kcov/issues/355 ?

Here is the output of Cmake which appears to find curl installed

However after running make I get the following error
