992 download boost libs with URL instead of git repo

[dabele]

Changes and Information

Download boost libs from a URL instead of git repository, archive download is much faster. Removed the bootstrapping code. With this increased speed, a minimal boost version is not necessary and not worth the maintenance.

Results from CI: compile times (with ccache and boost URL download) are down to ~4 mins, before they were at 20+. Obviously depends on many ccache hits and misses there are.

Not using the URL from github (e.g. https://github.com/boostorg/boost/archive/refs/tags/boost-1.84.0.tar.gz) since those archives don't actually contain the source code. I think the archive generation is automated, but the boost repo requires more setup before it is complete (subrepos, bootstrapping).

Checks by code author

• Every addressed issue is linked (use the "Closes #ISSUE" keyword below)
• New code adheres to coding guidelines
• No large data files have been added (files should in sum not exceed 100 KB, avoid PDFs, Word docs, etc.)
• Tests are added for new functionality and a local test run was successful (with and without OpenMP)
• Appropriate documentation for new functionality has been added (Doxygen in the code and Markdown files if necessary)
• Proper attention to licenses, especially no new third-party software with conflicting license has been added
• (For ABM development) Checked benchmark results and ran and posted a local test above from before and after development to ensure performance is monitored.

Checks by code reviewer(s)

• Corresponding issue(s) is/are linked and addressed
• Code is clean of development artifacts (no deactivated or commented code lines, no debugging printouts, etc.)
• Appropriate unit tests have been added, CI passes, code coverage and performance is acceptable (did not decrease)
• No large data files added in the whole history of commits(files should in sum not exceed 100 KB, avoid PDFs, Word docs, etc.)
• On merge, add 2-5 lines with the changes (main added features, changed items, or corrected bugs) to the merge-commit-message. This can be taken from the briefly-list-the-changes above (best case) or the separate commit messages (worst case).

Those new build times look great! We went from around 15 minutes down to about 3 for the linux builds in only two patches.

I have no objections, we can merge this once the CI passes.

@reneSchm @dabele What's the time reduction for download itself?

@lenaploetzke just FYI :)

What's the time reduction for download itself?

archive download is a < 10 secs, git clone is 1-2 mins, rough estimate, I didn't measure exactly.
