I haven't used CLion so can't comment on that, but I have tried a few other alternatives. QT Creator [1] has always worked very well for me. If you want to stick with vim there is YouCompleteMe[2]. You can also try using any editor that supports the LanguageServer protocol [3] and then use a C++ language server to provide cross references, hierarchies, completion and more. Microsoft has a language server plugin for vscode [4], there is also CCLS [5], cquery [6] or clangd [7] which can be made to work with both vim and emacs.
