    I am compiling qt from source and during configuration it fails a configuration step where it compiles some test programs, in my case "try_compile-v1".

    I would like to debug why this is, but the test programs are deleted upon failure, in-fact all of a folder called CMakeScratch is deleted.

    Does any one know the configuration switch to NOT delete these test programs so I can debug. I am 99% sure I have seen it before but can't find it anywhere.

      See cmake help:

      λ cmake --help | grep debug
        --debug-trycompile           = Do not delete the try_compile build tree.
        --debug-output               = Put cmake in a debug mode.
        --debug-find                 = Put cmake find in a debug mode.
        --debug-find-pkg=<pkg-name>[,...]
                                     = Limit cmake debug-find to the
        --debug-find-var=<var-name>[,...]
                                     = Limit cmake debug-find to the
