TODO: Not all targets, which will be added in the future, require
Boost. Therefore, a proper check will be appropriate here.

Implementation notes:
Although only Boost headers are used to build Bitcoin Core,
we still leverage a standard CMake's approach to handle
dependencies, i.e., the Boost::headers "library".
A command target_link_libraries(target PRIVATE Boost::headers)
will propagate Boost::headers usage requirements to the target.
For Boost::headers such usage requirements is an include
directory and other added INTERFACE properties.
