Comment (by ryandesign):

 If pgpointcloud links with an icu library, it should declare a dependency
 on it. And it should do so with a path:-based dependency so that icu-devel
 could satisfy it.

 Even better: use `xml2-config --libs --dynamic` instead of `xml2-config
 --libs` so that you don't pull in icu and other transitive dependencies
 and then remove those dependencies.

 Even better: use `pkg-config libxml-2.0 --libs` and then remove those
 dependencies.
