Export: Report error on relative include with genex. 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.

CMP0041
-------
Error on relative include with generator expression.
Diagnostics in CMake 2.8.12 and lower silently ignored an entry in the
:prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` of a target if it contained a generator
expression at any position.
The path entries in that target property should not be relative. High-level
API should ensure that by adding either a source directory or a install
directory prefix, as appropriate.
As an additional diagnostic, the :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` generated
on an :prop_tgt:`IMPORTED` target for the install location should not contain
paths in the source directory or the build directory.
The OLD behavior for this policy is to ignore relative path entries if they
contain a generator expression. The NEW behavior for this policy is to report
an error if a generator expression appears in another location and the path is
relative.
Help: Change version 3.0.0 -> 3.0 in policy docs 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.

|release| warns when the policy is not set and uses OLD behavior. Use
the cmake_policy command to set it to OLD or NEW explicitly.
