dxr-index.cpp is ~600 lines, so it's not enormous. It seems non-trivial
to get everything set up. Easy enough to build, though.

(Interestingly it's a clang plugin rather than a standalone using
libclang. (As is include-what-you-use.)

I wonder if that's a trend: that while it seems attractive to build a
standalone against a library with a reasonably stable and documented C
API, in practice it's easier to build a plugin because that lets you use
a richer set of classes and (likely more interesting?) makes it easier
to plug in to existing build systems, so it'll be easier for people to
use in their own projects.)
