Disallow use of the LOCATION property for build targets.
|
|
|
|
CMake 2.8.12 and lower allowed reading the :prop_tgt:`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 :genex:`$<TARGET_FILE>` generator
|
|
expression can be used to determine the eventual :prop_tgt:`LOCATION` of a target
|
|
output.
|
|
|
|
Code which reads the :prop_tgt:`LOCATION` target property can be ported to
|
|
use the :genex:`$<TARGET_FILE>` generator expression together with the
|
|
:command:`file(GENERATE)` subcommand to generate a file containing
|
|
the target location.
|
|
|
|
The ``OLD`` behavior for this policy is to allow reading the :prop_tgt:`LOCATION`
|
|
properties from build-targets. The ``NEW`` behavior for this policy is to
|
|
not to allow reading the :prop_tgt:`LOCATION` properties from build-targets.
|
|
|
|
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 :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
