"/Volumes/amm-er" -- what happens if you move the source and build trees onto your Mac hard drive and then try? Hopefully that will eliminate the linker crash. Maybe there's a linker error that only shows up when the build tree is a network mount, or whatever "amm-er" is... This is a problem with Apple's linker, not a problem with CMake. (As far as I can tell from the information in this thread...) HTH, David
