Thank you Raphael, it worked!<br>
<br>
One last question: i've tried to compile my code using static linkage, once<br>
i need my daemon runs in many Linux releases. But, even static, in many<br>
systems my code crashes because the GLIBC version.<br>
<br>
My question is: asking for static linkage in CMake can solve this problem?<br>
Or maybe another approach in CMake, where i embed all the needed<br>
libraries...<br>
<br>
Thanks for your attention!<br>

You need to find OpenSSL with `find_package(OpenSSL)' and then, assuming<br>
it is found (ie. OPENSSL_FOUND is true), link to its libraries with<br>
`target_link_libraries(YOUR_<u></u>APP ${OPENSSL_LIBRARIES})'.<br>

After the issues with glibc were already mentioned, be also aware that static linking to openssl is really not recommended. Just look at the history of security updates to openssl. Do you really want to ship a new executable on every update of any statically linked library? Probably not.<br>
The only good reason these days to link statically is maybe some performance hit shared libraries.<br><font color="#888888">
