Summary0014964: Command line scanning is bad with spaces
DescriptionIf the -D or -C options are used with a space between the flag and the argument after the path to the project, cmake will interpret the argument to the flag as being the intended source directory.
Steps To Reproducecmake . -D OPTION=VALUE # verbatim, run anywhere
cmake . -C initial-script # idem
Additional InformationWorks fine with -DOPTION=VALUE or -Cinitial-script or if the options are placed (with spaces) before the build directory.

This works fine for me, especially if I follow the correct syntax and specify the path to the source directory last.

I am aware that the correct syntax is with the source directory last, but I think that placing options afterwards should either always work or never work, because working only without a space is a rather odd quirk.

It's also not particularly obvious that the source directory has to be the last argument.

Bump -- I still think it would be good if CMake were less obtuse about this -- perhaps *consistently* outputting an error message if there's anything else after the source directory, or if the behaviour were at least clearly documented.

Moving to backlog because no one is working on it.

The command-line argument handling needs a non-trivial cleanup anyway to do things like complain about unrecognized options. This issue is just one of symptoms.
