Is _d prefix actually needed? That is:

- is linking to release version of ICU gonna cause problems due to
ABI changes?
- is _d prefix used by official distribution of ICU?

If so, it's easy to change.

I recommend you wait for a week. While it's certainly possible to
improve ICU autodetection for your library, an convenient and consistent
interface for such checks was one of my goals for 1.43 and is being
designed right now.

You would use <include>whatever or <library-path>whatever in the requirements
of Jamroot, or in project-config.jam
