Cmake-tools does not display included cmake files

[inxksp]

Brief Issue Summary

Cmake-tools does not display included cmake files - "include (somefile.cmake)". Although cmake creates a response .cmake\api\v1\reply\ cmakeFiles-v1-xxx.json which has full information about them.
For example it could look like this (Qt Creator - creates a full Cmake files structure in a separate folder):

This is very convenient for working with a cmake project, and not just with source code files.

@inxksp Thanks for the suggestion, we are currently planning work for some time in the future around the Project Outline view, and we will make sure to take this into consideration! I'll link this to our current Project Outline issue #3565, and close this issue. Thanks!
