c++ - Best practice for creating a SDK for which also uses public available frameworks -

recently i'm having many issues customers using our sdk, uses exact public available framework/libraries use. issue duplicate symbols.

for example, 1 reachability apple provides. solved adding compile time prefix class.

however, library example openssl lib, i'm have hard time solving.

when compiling sdk these public libraries, how can separate them own name spaces @ compile time? or how make separate public libraries?

thanks
