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. 2016-06-02 17:57:10 +03:00			`enable_language(C)`
