Unexpected stderr/stdout on load initial cache file in output

Brief Issue Summary

I try to load a project which use init cache files on configuration.

settings.json: cmake.configureArgs": [ -C...cmake]

The configuration works but the cms-client provides a unexpected stderr/stdout.

[cms-client] Unexpected stderr/stdout data from CMake Server process: loading inital cache file .....cmake

Expected:

No unexpected warning

Platform and Versions

• Operating System:Windows 10
• CMake Version: 3.10.0

With CMake 3.11, I also get these warnings using default settings (cmake.configureArgs is not set).

Is there a solution to this ? I saw this but haven’t had the time to try it OUTPUT_STRIP_TRAILING_WHITESPACE https://stackoverflow.com/questions/13037230/how-do-i-initialize-a-cmake-variable-with-the-result-of-a-shell-command
