Unfortunately, this is trickier than it should be. You can take a
look at how the kyua-cli package jumps through the necessary hooks to
get this working... but it's not pretty. Basically, there is a script
to populate the build tree with copies of the Kyuafiles, just as if
they were products of the build. It works, but it's extra complex.
Ideas on how to simplify this would certainly be welcome.

At the moment, the *_test_program definitions restrict the test
programs to live in the same directory as the Kyuafile that references
them; passing paths will not work. I'm not convinced this is the most
reasonable solution, but I like its simplicity.
Having Kyuafiles pointing at arbitrary directories could make things
more confusing. For example, how do you identify the test programs
within that Kyuafile? By their basename? Or should there be an
additional "binary" attribute to the test program that can be a path,
and "name" is just the identifier? How are these represented for
historical purposes in the database?
Another possibility that just crossed my mind (and that I think makes
a lot of sense atually) would be to teach "kyua test" about build
directories: allow the caller to specify a destdir/buildroot and use
that as the prefix to locate the binaries themselves (not the
Kyuafiles). This would be more in line with make's behavior and some
other build tools I have used. The issue here would be dealing with
programs that reference data files in the program's srcdir: if the
data file needs some kind of "build", then it will be in the
buildroot; otherwise, it will be in the source tree. But we could
deal with that somehow!
What do you think?

Configuration variables are not exposed to Kyuafiles. I guess it
would make sense to do so though.
