Are you calling tar via a custom command? tar itself looks to have
a few options to print progress:<br>
<br>

<br>
Although none of the options seem to know the archive's size, so
aren't able to print a completion percentage.<br>

<div>It's awkward to wait 30-60 minutes for file untarring
with absolutely 0 information. I'm not aware of any way to
do this through CMake directly, only alternative is e.g.
python script that does the untar for me.</div>
