INTERFACE_LINK_LIBRARIES

List public interface libraries for a library.

This property contains the list of transitive link dependencies. When the target is linked into another target using the target_link_libraries() command, the libraries listed (and recursively their link interface libraries) will be provided to the other target also. This property is overridden by the LINK_INTERFACE_LIBRARIES or LINK_INTERFACE_LIBRARIES_<CONFIG> property if policy CMP0022 is OLD or unset.

Contents of INTERFACE_LINK_LIBRARIES 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.

Note

A call to target_link_libraries(<target> ...) may update this property on <target>. If <target> was not created in the same directory as the call then target_link_libraries() will add a suffix of the form ::@<directory-id> to each entry, where the ::@ is a separator and the <directory-id> is unspecified. This tells the generators that the named libraries must be looked up in the scope of the caller rather than in the scope in which the <target> was created. Valid directory ids are stripped on export by the install(EXPORT) and export() commands.

Creating Relocatable Packages

Note that it is not advisable to populate the INTERFACE_LINK_LIBRARIES of a target with absolute paths to dependencies. That would hard-code into installed packages the library file paths for dependencies as found on the machine the package was made on.

See the Creating Relocatable Packages section of the cmake-packages(7) manual for discussion of additional care that must be taken when specifying usage requirements while creating packages for redistribution.
