targets. See the IMPORTED mode of the add_library command for more
information.
Library dependencies are transitive by default. When this target is
linked into another target then the libraries linked to this target
will appear on the link line for the other target too. See the
INTERFACE_LINK_LIBRARIES target property to override the set of
transitive link dependencies for a target. Calls to other signatures
of this command may set the property making any libraries linked

Library dependencies are transitive by default with this signature.
When this target is linked into another target then the libraries
linked to this target will appear on the link line for the other
target too. This transitive "link interface" is stored in the
INTERFACE_LINK_LIBRARIES target property when policy CMP0022 is set to
NEW and may be overridden by setting the property directly.
(When CMP0022 is not set to NEW, transitive linking is builtin but may
be overridden by the LINK_INTERFACE_LIBRARIES property. Calls to other
signatures of this command may set the property making any libraries
linked exclusively by this signature private.)
CMake will also propagate "usage requirements" from linked library
targets. Usage requirements affect compilation of sources in the
