Download a hyprcursor theme and extract it to a new directory in ~/.local/share/icons
.
Make sure the first directory contains a manifest, for example:
~/.local/share/icons/myCursorTheme/manifest.hl
Set the HYPRCURSOR_THEME
env to your theme directory,
so for example to get the above to always load, use export HYPRCURSOR_THEME = myCursorTheme
.
