+  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.
