To build the testsuite, you need to define XAPIAN_LIB_BUILD as a C
preprocessor symbol (this allows you to include parts of the Xapian
header system, rather than all of them). xapian-core does this
throughout, but you probably want to do this just while building the
tests (probably add it to AM_CPPFLAGS in tests/Makefile.am).

I think for the testsuite this is mainly for common/output.h, which is
basically just creating some overloaded operators so you can easily
write Xapian objects to a std::ostream like stderr and have them
display sensibly.
