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.

The target in the TARGET signature of add_custom_command() must exist.
|
|
|
|
CMake 2.8.12 and lower silently ignored a custom command created with
|
|
the TARGET signature of :command:`add_custom_command`
|
|
if the target is unknown.
|
|
|
|
The OLD behavior for this policy is to ignore custom commands
|
|
for unknown targets. The NEW behavior for this policy is to report an error
|
|
if the target referenced in :command:`add_custom_command` is unknown.
|
|
|
|
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.
