Bumping the version from 0.2.0-0ubuntu1 to 0.2.0-0ubuntu2 was unnecessary as 0.2.0-0ubuntu1 was marked UNRELEASED, so you could change that back.
No SONAME change required? I assume you've checked whether mir's ABI is affected. Also assume you've double-checked that cmake picks up CC and CXX from its environment.
The include /usr/share/dpkg/default.mk is unnecessary, since DEB_HOST_ARCH was already defined above.
