I would like to add src files to the proj without building ALL of them!

By not including everything in main.cpp. Instead use correct C++ programming, including header files in cpp files that need them. That way C::B will compile only changed files.

Your comment is not constructive!
The OP might have his reasons to do what he is trying to do.

For example I know that SQLite people has a mode for building in this way and they gain some performance from it
(because the compiler can see all the function and do its magic).

Please explain more about this magic. How doesn't compiler "see" all functions in any cases?

Likely code optimization is made easier by seeing all the code at once.
But, the main reason I think SQLite uses a single effective c/c++ file is ease of use is improved for some cases.

The compiler can optimize better, because it sees all functions and code, so it can do better inlining, const propagation, etc. You get the same benefits like with the newer -flto flag.
