Description:
Trying to build an image with libmosquittopp included and keep running into this issue:

Package libmosquittopp is missing dependencies for the following libraries:
libmosquitto.so.1

This problem has been occurring me for quite some time, we've talked about it in IRC before but never found a fix. This happens after make dirclean. I usually work around it with this hack:

diff --git a/include/package-ipkg.mk b/include/package-ipkg.mk
index c374faa647..49feb97d4d 100644
--- a/include/package-ipkg.mk
