That one doesn't have to be delayed until generation time, but if we did have generate-time conditionals they could be used for this. We're in agreement that this is turning into a declarative spec. If we keep the evaluation of it at generate time then there is no chance that imperative logic will conflict because the imperative part runs only during the configuration step. > I thought maybe we can discard the idea of using generator expressions built > into the property content, and introduce a new finalize() command similar to > macro() and function(): It would have to run once for each configuration to be generated and receive said configuration as an argument. The implementation would have to fork the entire representation into independent per-configuration branches (cmMakefile, cmTarget, etc.). It would also allow imperative logic after the end of configuration or during generation time which should be avoided for the reason above. -Brad -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
