LIB_DEPENDS affects building of the port and the run dependencies registered
in the resulting package.

It tests for the existence of a library, while BUILD_DEPENDS check for a file
and RUN_DEPENDS check for an installed package (possibly restricted to some
range of versions of the package).

Just use:


This will make sure that library is available when building the port and it
will register a run dependency on the package that provides that library in
the package built by your port.


for all the details ...
