Note that it is not advisable to populate the ``INSTALL_INTERFACE`` of the
|INTERFACE_PROPERTY_LINK| of a target with paths for dependencies.
That would hard-code into installed packages the include directory paths
for dependencies **as found on the machine the package was made on**.
The ``INSTALL_INTERFACE`` of the |INTERFACE_PROPERTY_LINK| is only
suitable for specifying the required include directories of the target itself,
not its dependencies.
That is, code like this is incorrect for targets which will be used to
generate :manual:`cmake-packages(7)`:
.. code-block:: cmake
target_include_directories(mylib INTERFACE
$<INSTALL_INTERFACE:${Boost_INCLUDE_DIRS};${OtherDep_INCLUDE_DIRS}>
)
Dependencies must provide their own :ref:`IMPORTED targets <Imported Targets>`
which have their own |INTERFACE_PROPERTY_LINK| populated
appropriately. Those :ref:`IMPORTED targets <Imported Targets>` may then be
used with the :command:`target_link_libraries` command for ``mylib``.
That way, when a consumer uses the installed package, the
consumer will run the appropriate :command:`find_package` command to find
the dependencies on their own machine and populate the
:ref:`IMPORTED targets <Imported Targets>` with appropriate paths. See
:ref:`Creating Packages` for more. Note that many modules currently shipped
with CMake do not currently provide :ref:`IMPORTED targets <Imported Targets>`.
