Hi Bas,

all done, but stuck at the last:

Tried a lot around adding to debian/rules something like this:

```
CPPFLAGS:=$(shell dpkg-buildflags --get CPPFLAGS)
CXXFLAGS := $(shell dpkg-buildflags --get CXXFLAGS) $(CPPFLAGS)
export CXXFLAGS
```

but as far as I read with compat > 9 (which we are that should be handled already).

Do you have any suggestion or which package to look at on how it has been done?

Thanks,
Felix
