* Help: Document explicitly that policy OLD behavior is deprecatedBrad King2015-06-091-0/+2
| | | | | | | | | | | The most likely documentation page a project author will read in response to a policy warning is the page for the policy itself. Add to every policy documentation page a note explicitly stating that the OLD behavior is deprecated. Also mention this in the cmake_policy() command documentation that explains how to set a policy to OLD. Suggested-by: Fraser Hutchison <fraser.hutchison@gmail.com>
* Help: Change version 3.0.0 -> 3.0 in policy docsBrad King2014-02-101-1/+1
| | | | | | Starting with 3.0 we will use only two components for the feature level, and policies are only ever introduced with a bump to the feature level version.
* Export: Report error on relative include with genex.Stephen Kelly2013-11-261-0/+25
Diagnostics which check the sanity of exported include paths previously skipped over any path containing a generator expression. Introduce a policy to issue an error message in such cases. The export files created in the OLD behavior are not usable, because they contain relative paths or paths to the source or build location which are not suitable for use on installation. CMake will report an error on import.
