This is a good tip and is something I have wanted to do on a different project but didn't know how, but it seems that it doesn't work if you use EXCLUDE_FROM_ALL. The install_manifest file for the component is empty if it was created in the subdirectory. So while you can use EXCLUDE_FROM_ALL to add a directory that you can build on demand, it seems that installing the items in the folder on demand is not possible. However, I think I can use a combination of these techniques: EXCLUDE_FROM_ALL only on the targets instead of the directories, and executing the cmake_install.cmake script by hand to get most of what I need. -- Daniel _______________________________________________ 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://www.cmake.org/mailman/listinfo/cmake
