CMake can't find C or CXX compiler if Xcode has a space in the name
I thought I should note this down as it confused me. If you have Xcode with a space in the name (e.g. "Xcode-beta 2.app") then the compiler detection cannot find the paths. I used xcode-select -s
to set my default xcode to "Xcode-beta 2.app" in my downloads folder. I added a debug print to CMakeDetermineCompilerId.cmake and _comp
came out as /Users/hmallon/Downloads/Xcode-beta\
(skipping everything after the escaped space).
% cmake -GXcode ../
