If all my compile environment on a remote server, can I use CLion's full feature like code-completion, static analysis, and symbol navigation?

I know CLion understand code depends on CMake, but does it need a real compiler to do something? If I only have Makefile and CMake, can CLion analyze my source code well?

I found that CLion support working with Makefiles by using Compilation DB, but it looks like need to find compiler and compile my source code. I also try to use CMake to call a local Makefile (but Makefile won't do real work), but CLion does not work well.

Many tools can analyze source code by itself althought it don't know some compiler configuration or macros. Can CLion do that just with CMake (no compiler), theoretically?
