The ctest_upload
<https://cmake.org/cmake/help/latest/command/ctest_upload.html> command may
suit your needs. This allows you to upload arbitrary files and associate
them with your build. Note that you can also upload a text file with the
".url" extension and CDash will display it as a link instead of a file to
download.

If you do end up needing to use a separate tool, I recommend that you take
a look at girder <https://github.com/girder/girder>, Kitware's data
management platform.
