Trying to build Falkon Browser from Source

Hello, the build works fine on my Debian machine, but I have one question.

According to AUR, Falkon requires the package libgnome-keyring.

On Debian this package has been deprecated since 2019 and replaced by libsecret.
I get the following warning from cmake because of this:

-- Checking for module 'gnome-keyring-1'
--   Package 'gnome-keyring-1', required by 'virtual:world', not found

The build still completes successfully because it’s optional, but I noticed that some icons are missing which are probably supplied by this gnome package too.

Should I file a bug report or is there another way to fix this? Since Falkon can be installed from the Debian main repo I wonder how they’ve solved this issue. Anyway, thank you in advance.

Kind regards,

Jim
