CMP0040
|
||||
-------
|
||||
|
||||
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 and error
|
||||
if the target referenced in :command:`add_custom_command` is unknown.
|
||||
|
||||
This policy was introduced in CMake version 3.0.0. 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.
