I usually copy (or extract zipfile) to the hidden folder (you may need to create this first) ~/.fonts/ and then run the command fc-cache -f -v and the fonts are now "installed" for your user, but if you want them available for all users you could put them in the folder /usr/local/share/fonts/ and then fun the fc-cache command to update them.I know this is not a "one-click solution" but it is how I have done it for years is easy and reliable.
