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>

-------

|
|
Target names should not be reserved and should match a validity pattern.
|
|
|
|
CMake 2.8.12 and lower allowed creating targets using :command:`add_library`,
|
|
:command:`add_executable` and :command:`add_custom_target` with unrestricted
|
|
choice for the target name. Newer cmake features such
|
|
as :manual:`cmake-generator-expressions(7)` and some
|
|
diagnostics expect target names to match a restricted pattern.
|
|
|
|
Target names may contain upper and lower case letters, numbers, the underscore
|
|
character (_), dot(.), plus(+) and minus(-). As a special case, ALIAS
|
|
targets and IMPORTED targets may contain two consequtive colons.
|
|
|
|
Target names reserved by one or more CMake generators are not allowed.
|
|
Among others these include "all", "help" and "test".
|
|
|
|
The OLD behavior for this policy is to allow creating targets with
|
|
reserved names or which do not match the validity pattern.
|
|
The NEW behavior for this policy is to report an error
|
|
if an add_* command is used with an invalid target name.
|
|
|
|
This policy was introduced in CMake version 3.0. CMake 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.
