The generator expression stops parsing at whitespace. I believe you're hitting a problem related to what is discussed in this thread: http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/7063 It will require patching CMake, but there is no one working on a patch yet. http://public.kitware.com/Bug/view.php?id=14353 Thanks, Steve. -- 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.

[cmake-developers] generator expressions with variable
hi all, i'm trying to obtain the include paths from a target via a generator expression, which is adapted from the help file: help: $<$>:-I$, -I>> i adapted it to obtain the value from a target, which is passed as a function argument: $<$>:-I$, -I>> however evaluating the expression results in this command string: $<1:-I$> is this a bug or a feature? thanks a lot, tim -- 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.
