I think your approach is the usual one.  See, e.g., x11/libfm-qt for
a similar example.

This came up a lot more about a year ago when we started to sanitize
the paths that cmake looks for, just like we've long done for
non-cmake build systems, to detect undeclared dependencies that will
cause trouble later on down the line.  Erstwhile discussion of some of
the fallout:

https://mail-index.netbsd.org/tech-pkg/2024/12/25/msg030256.html

Not sure if the INTERFACE_LINK_LIBRARIES issue in particular was
discussed publicly, might have only been in private mail.  But some
packages already had this workaround, like textproc/libkolabxml from
2021.
