CMake 3.14 +and later will evaluate generator expressions for :command:`install(CODE)` and +:command:`install(SCRIPT)`. + +The ``OLD`` behavior of this policy is for :command:`install(CODE)` and +:command:`install(SCRIPT)` to not evaluate generator expressions. The ``NEW`` +behavior is to evaluate generator expressions for :command:`install(CODE)` and +:command:`install(SCRIPT)`. + +Note that it is the value of this policy setting at the end of the directory +scope that is important, not its setting at the time of the call to +:command:`install(CODE)` or :command:`install(SCRIPT)`. This has implications +for calling these commands from places that have their own policy scope but not +their own directory scope (e.g. from files brought in via :command:`include()` +rather than :command:`add_subdirectory()`). + +This policy was introduced in CMake version 3.14. 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. + +.. include:: DEPRECATED.txt |
