This tells CMake to generate a single argument consisting of the entire expanded value. We have no syntax to expand lists into multiple command line arguments after evaluation of generator expressions. Without the quotes the "$<" and ">" parts appear in different arguments to add_custom_command and so it is not recognized as a generator expression. It is not currently possible to do what you are trying to do. You'll need to use file(GENERATE) to produce a script holding the desired command instead. Then launch the script as the custom target's command. -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.
