Added in version 3.14.
install(CODE) and install(SCRIPT) support generator
expressions.
In CMake 3.13 and earlier, install(CODE) and
install(SCRIPT) did not evaluate generator expressions. CMake 3.14
and later will evaluate generator expressions for install(CODE) and
install(SCRIPT).
The OLD behavior of this policy is for install(CODE) and
install(SCRIPT) to not evaluate generator expressions. The NEW
behavior is to evaluate generator expressions for install(CODE) and
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
install(CODE) or 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 include()
rather than add_subdirectory()).
This policy was introduced in CMake version 3.14.
It may be set by cmake_policy() or cmake_minimum_required().
If it is not set, CMake warns, and uses OLD behavior.
Note
The OLD behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
