6Reject source and build dirs in installed
7:prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES`.
8
9CMake 3.0 and lower allowed subdirectories of the source directory or build
10directory to be in the :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` of
11installed and exported targets, if the directory was also a subdirectory of
12the installation prefix.  This makes the installation depend on the
13existence of the source dir or binary dir, and the installation will be
14broken if either are removed after installation.

16See :ref:`Include Directories and Usage Requirements` for more on
17specifying include directories for targets.
18
19The ``OLD`` behavior for this policy is to export the content of the
20:prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` with the source or binary
21directory.  The ``NEW`` behavior for this
22policy is to issue an error if such a directory is used.
23
24This policy was introduced in CMake version 3.1.
25CMake version |release| warns when the policy is not set and uses
26``OLD`` behavior.  Use the :command:`cmake_policy` command to set it
27to ``OLD`` or ``NEW`` explicitly.
