New 3.13-rc1 genex support in install(CODE|SCRIPT) may break legacy script code
Given the following contrived example
cmake_minimum_required(VERSION 3.11)
project(Foo NONE)
install(CODE [[
message("$<FOOBAR>")
]])
This will configure without error in e.g 3.11 but starting with 3.13-rc1 it will produce the following error:
CMake Error:
Error evaluating generator expression:
$<FOOBAR>
Expression did not evaluate to a known generator expression
This probably isn't too difficult to work around in existing code and may even be rare but may warrant a policy?
