Fix crash on $<TARGET_PROPERTY:...,LOCATION> genex (#16134) Policy CMP0026 deprecated the LOCATION property, and we have long provided a $<TARGET_FILE:...> generator expression. However, if a project tries to use $<TARGET_PROPERTY:...,LOCATION> we should at least not crash. The compatibility implementation of the LOCATION property uses cmGlobalGenerator::CreateGenerationObjects to create the structures needed to evaluate the property before generation starts. The implementation assumed that accessing the property could only be done during configuration (via the typical get_property command use case). The $<TARGET_PROPERTY:...,LOCATION> genex causes the LOCATION property to be accessed during generation. Calling CreateGenerationObjects during generation blows away all the objects currently being used for generation and is not safe. Add a condition to call it only when configuration is not finished.

CMake Warning \(dev\) in CMakeLists.txt:
Policy CMP0026 is not set: Disallow use of the LOCATION target property.
Run "cmake --help-policy CMP0026" for policy details. Use the cmake_policy
command to set the policy and suppress this warning.
The LOCATION property should not be read from target "foo". Use the target
name directly with add_custom_command, or use the generator expression
\$<TARGET_FILE>, as appropriate.
This warning is for project developers. Use -Wno-dev to suppress it.
