[CMake] Undefined reference

[Mauricio Klein]

Thank you Raphael, it worked!

One last question: i've tried to compile my code using static linkage, once
i need my daemon runs in many Linux releases. But, even static, in many
systems my code crashes because the GLIBC version.

My question is: asking for static linkage in CMake can solve this problem?
Or maybe another approach in CMake, where i embed all the needed
libraries...

Thanks for your attention!
