[CMake] cmake env - no command given

[Petr Kmoch]

Hi Lars.

No, that's a "bug" in your command-line. In cmd, the caret ^ is used as a
general escape character for escaping spaces, pipes etc. But to escape
quotes, a backslash \ is used (yes, the escaping rules in cmd are weird).
So the backslash preceding the quote is taken by cmd to be an escape
character, and the quote becomes a literal quote character instead of
terminating the argument. You're left without a closing quote, which cmd
apparently auto-fill, so you end up passing the string `PATH=C:\temp" calc`
as one argument, and no other argument.

If you need the backslash before the quote, you need to double it:

"C:\Program Files (x86)\CMake\bin\cmake.exe" -E env "PATH=C:\temp\\" calc
