cmake-2.8.6 has the following documentation of the
LINK_INTERFACE_LIBRARIES property for targets:
LINK_INTERFACE_LIBRARIES
List public interface libraries for a shared library or executable.
By default linking to a shared library target transitively links to
targets with which the library itself was linked. For an executable
with exports (see the ENABLE_EXPORTS property) no default transitive
link dependencies are used. This property replaces the default
transitive link dependencies with an explicit list. When the target
is linked into another target the libraries listed (and recursively
their link interface libraries) will be provided to the other target
also. If the list is empty then no transitive link dependencies
will
be incorporated when this target is linked into another target
even if
the default set is non-empty. This property is ignored for STATIC
libraries.
I believe the reference to executables above is just plain
wrong/misleading. For example, the FAQ states that
LINK_INTERFACE_LIBRARIES simply lists "the libraries that should be
transitively included in the link by CMake" with the clear implication
(also confirmed by experiment below) that this target property affects
_everything that links to the target whose property is being set_.
But nothing links to an executable so why are executables mentioned at
all?
That's not true. See the ENABLE_EXPORTS target property.
Oops. You are right. I had never ever heard of applications
exporting symbols before. Live and learn.
