Notes for Reviewer

@dkroenke I create this PR to address issue #1368 .

I am using cmakelang and have some open points stll:

1. The linter/formatter file in this PR contains the default config used by the tools, I just changed the tab size to 4 instead of 2, I think we need to revisit this config as applying them locally drastically changed the files.
2. CI is not yet configured with the format/lint step, I will address this in later commits.

The copyright header should not be reformatted.

I think I will need to fence this block from formatting, so disabling the formatter before it and then enable it after

[dkroenke]

Can we have an additional layer additional indentation?

I tried my best to maintain the same form of indentation, but it seems that I do not have a control on the number of spaces/tabs between the columns. Please check the last commit

[dkroenke]

I guess the formatter interprets this as comment, maybe another separator symbol would be good

[zmostafa]

The formatter forces a space between the comment mark and the being of the comment, I am disabling the format before this section as a solution,what do you think ?

@zmostafa are you planing to continue working on this PR?

[zmostafa]

@elBoberido Yes, I am waiting for @dkroenke 's feedback for the new format, since applying cmake lint will change the current files format.
