Disallow use of the LOCATION property for build targets.
CMake 2.8.12 and lower allowed reading the LOCATION target property (and configuration-specific variants) to determine the eventual location of build targets. This relies on the assumption that all necessary information is available at configure-time to determine the final location and filename of the target. However, this property is not fully determined until later at generate-time. At generate time, the $<TARGET_FILE> generator expression can be used to determine the eventual LOCATION of a target output.
Code which reads the LOCATION target property can be ported to use the $<TARGET_FILE> generator expression together with the file(GENERATE) subcommand to generate a file containing the target location.
The OLD behavior for this policy is to allow reading the LOCATION properties from build-targets. The NEW behavior for this policy is to not to allow reading the LOCATION properties from build-targets.
This policy was introduced in CMake version 3.0. CMake version 3.9.6 warns when the policy is not set and uses OLD behavior. Use the cmake_policy command to set it to OLD or NEW explicitly.
Note
The OLD
behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
