# INTERFACE_LINK_DEPENDS

Additional public interface files on which a target binary depends for linking.

This property is supported only by `Ninja` and Makefile Generators. It is intended to specify dependencies on “linker scripts” for custom Makefile link rules.

When target dependencies are specified using `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 `cmake-generator-expressions(7)` manual for available expressions. See the `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:

    set_property(TARGET mylib PROPERTY INTERFACE_LINK_DEPENDS
      $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/mylinkscript>
      $<INSTALL_INTERFACE:mylinkscript>  # <prefix>/mylinkscript
    )
