Note that BH is _headers-only_ and hence works by LinkingTo: (which despite its name is NOT used for linking) which covers "most" of the Boost functionality (but eg not Boost graph used in RBGL on BioC). In general the problem you describe is "hard". See Writing R Extensions, and use of SystemRequirements, plus possibly use of configure to detect library presence at the compile-time of you package.
