It hasn't been implemented. At least at one time it would have been very hard to implement. I'm not sure now because there has been a lot of refactoring since I last looked at it. There is some discussion here: https://cmake.org/Bug/view.php?id=13840 https://cmake.org/Bug/view.php?id=12877#c28315 > If I can't use generator expressions with ``OUTPUT``, how am I > supposed to output a file into the build directory of a target? Unfortunately it is not possible to do cleanly without fixing the above. Approximations include: * Use a POST_BUILD command on the target instead. * Make the OUTPUT a timestamp file and generate the real output as a side effect. If anyone is interested in trying to implement generator expressions for custom command outputs, I can provide more details to get started. -Brad -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
