On macOS, this change ensures that the Boost package is located at its real path rather than via the symlink in the default prefix.

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.
