I took the rules file of libpng as an example and also understood from [1]
that I have to use an override for dh_install to dynamically update the
install path through the environment variable DEB_HOST_MULTIARCH.
I found the solution a bit strange myself, but since it is stated like that in the
wiki and also done this way for libpng, I thought it would be the correct way.

The guide also says:
"If /usr/lib (or a subdirectory) is listed as an installation target in debian/*.install, or the target of a link in debian/*.links, you will need to autogenerate this file in debian/rules with an override target (and add the generated files to debian/clean so they're removed again in the clean target), to substitute in the value of $(DEB_HOST_MULTIARCH)."

Yes, thanks a lot.
My understanding was that all the libraries go into /usr/lib/${DEB_HOST_MULTIARCH} with
nothing remaining in /usr/lib. When I check for libpng, there are no related files in /usr/lib
but in /usr/lib/${DEB_HOST_MULTIARCH}.
Or is the idea that there are still symlinks in /usr/lib which point to the native .so files.

So simply using ${DEB_HOST_MULTIARCH} in the libz80ex1.install file?
Thanks for your fast reply!
