| <p>Reject source and build dirs in installed INTERFACE_INCLUDE_DIRECTORIES.</p> |
| <p>CMake 3.0 and lower allowed subdirectories of the source directory or build |
| directory to be in the <span class="target" id="index-0-prop_tgt:INTERFACE_INCLUDE_DIRECTORIES"></span><a class="reference internal" href="../prop_tgt/INTERFACE_INCLUDE_DIRECTORIES.html#prop_tgt:INTERFACE_INCLUDE_DIRECTORIES" title="INTERFACE_INCLUDE_DIRECTORIES"><code class="xref cmake cmake-prop_tgt docutils literal"><span class="pre">INTERFACE_INCLUDE_DIRECTORIES</span></code></a> of |
| installed and exported targets, if the directory was also a subdirectory of |
| the installation prefix. This makes the installation depend on the |
| existence of the source dir or binary dir, and the installation will be |
| broken if either are removed after installation.</p> |
| <p>See <a class="reference internal" href="../manual/cmake-buildsystem.7.html#include-directories-and-usage-requirements"><span class="std std-ref">Include Directories and Usage Requirements</span></a> for more on |
| specifying include directories for targets.</p> |

| directory. The NEW behavior for this |
| policy is to issue an error if such a directory is used.</p> |
| <p>This policy was introduced in CMake version 3.1. |
| CMake version 3.8.2 warns when the policy is not set and uses |
