Debian package not including files; runs install during build

Question

I'm creating a Debian package for my application using dh/debuild, following Ubuntu's PackagingGuide/Complete but I'm having some trouble. I think it has to do with the structure of my Makefile. The source Makefile is:

install:
    mkdir -p /usr/share/getbooru
    cp -av * /usr/share/getbooru
    ln -s /usr/share/getbooru/getbooru /usr/bin/getbooru
remove:
    rm -rv /usr/share/getbooru /usr/bin/getbooru

The application is written in PHP so no compiling is needed. After running debuild -S to build the source Debian package, I then use debian/rules binary to create the binary package. These are the problems:

• the above install procedure (Makefile install target) is run during package build
• the resulting package does not contain my application files

Answer 1

You'd need to change the upstream Makefile so instead of installing to /usr/share/* it installs to debian/$packagename/usr/share.
