Thanks for the reply. I probably didn't give enough information on what I'm trying to do. I have an application that compiles in both Linux and Mac OS X. The majority of the code is user-space (all of which is portable), and the only niggling thing with the build system is the kernel stuff. There are Linux kernel modules, and a single Mac OS X kernel extension. Currently, the Linux kernel modules are built within CMake using a custom command to launch "Kbuild", the Linux kernel build system. I've had to manually specify each output file in order to aid cleaning, since Kbuild is in-source-tree (hence it spams my source tree). The Mac OS X kernel extension required me to use XCode to set up the build environment for kernel extensions, which use many compiler specifics/tricks. I don't really want to go down the route of attempting to compile the kext from _within_ CMake, as it would be costly in time to investigate this. Instead, I simply want to launch xcodebuild, and use the output as an install target for CPack to pick up on. Although by the looks of it, CPack isn't quite ready for our requirements.
