cmake: Improve error handling in `cmake -E tar` command (!3080) · Merge requests · CMake / CMake

This Merge Request is related to: #16834

With this Merge Request I would like to improve error handling by cmake -E tar, with following steps:

If archive needs to be created then list of files are mandatory. Otherwise error message will be displayed.
Update tar documentation with not described arguments.
During creation of archive, if one file cannot be read, then continue with adding next files. This is a mimic of original tar implementation.
