- -------
- Double colon in target name means ALIAS or IMPORTED target.
- CMake 2.8.12 and lower allowed the use of targets and files with double
- colons in target_link_libraries, with some buildsystem generators.
- The use of double-colons is a common pattern used to namespace IMPORTED
- targets and ALIAS targets. When computing the link dependencies of a target,
- the name of each dependency could either be a target, or a file on disk.
- Previously, if a target was not found with a matching name, the name was
- considered to refer to a file on disk. This can lead to confusing error
- messages if there is a typo in what should be a target name.
- The OLD behavior for this policy is to search for targets, then files on disk,
- even if the search term contains double-colons. The NEW behavior for this
- policy is to issue a FATAL_ERROR if a link dependency contains
- double-colons but is not an IMPORTED target or an ALIAS target.
- 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.
