INTERFACE_LINK_DEPENDS.rst
INTERFACE_LINK_DEPENDS
----------------------
Additional public interface files on which a target binary depends for linking.
This property is supported only by :generator:`Ninja` and
:ref:`Makefile Generators`.
It is intended to specify dependencies on "linker scripts" for
custom Makefile link rules.
When target dependencies are specified using :command:`target_link_libraries`,
CMake will read this property from all target dependencies to determine the
build properties of the consumer.
Contents of ``INTERFACE_LINK_DEPENDS`` may use "generator expressions"
with the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)`
manual for available expressions. See the :manual:`cmake-buildsystem(7)`
-manual for more on defining buildsystem properties.
Link dependency files usage requirements commonly differ between the build-tree
and the install-tree. The ``BUILD_INTERFACE`` and ``INSTALL_INTERFACE``
generator expressions can be used to describe separate usage requirements
based on the usage location. Relative paths are allowed within the
``INSTALL_INTERFACE`` expression and are interpreted relative to the
installation prefix. For example:
.. code-block:: cmake
set_property(TARGET mylib PROPERTY INTERFACE_LINK_DEPENDS
$<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/mylinkscript>
$<INSTALL_INTERFACE:mylinkscript> # <prefix>/mylinkscript
)
