Describe the bug
Seems like some updates to pango broke a few packages

Among the broken ones:

• ettercap (see ettercap: fix pango not finding hb.h from harfbuzz #75789)
• pangox-compat (which anydesk needs)
• probably a few more

To Reproduce
Steps to reproduce the behavior:

1. Try to build ettercap or anydesk from master
2. It will fail to build with some pango-related errors

Expected behavior
It should work
