cmake provides file-code completion in e.g. include_directories. But it can be easily confused with something like this:


Reproducible: Always

Steps to Reproduce:
set(someVar
  foo.cpp
)

- place cursor after the foo, before the dot
- request file code completion
- insert some file

Actual Results:  
set(someVar
  bar.cpp.cpp
)
(assuming you inserted bar.cpp)

Expected Results:  
set(someVar
  bar.cpp
)


something similar happens if you try to request code completion in the file extension, e.g. with the cursor somewhere in the .cpp part. It looks for files starting with cpp

The code completion model should overload some of the helper functions to add "." to the allowed chars.
