Summary0003612: Feature for graceful exiting
DescriptionI wish there was a way to exit a cmake script gracefully without raising a FATAL_ERROR.

Something like message(EXIT, "optional message")
that doesn't scare the user with a stack trace or indicate any errors at all.

Or maybe Exit(code)? where you exit with a code?

It is sometimes necessary for cmake to test things and terminate if the conditions aren't met.

For instance, when adding files to a project, it is possible to write macros so that a file is automatically created from a template file during the cmake process. It may be an error if the template for a given file type isn't found, which would warrant a termination with an error message. I've found that raising a MESSAGE(FATAL_ERROR "some error message") doesn't always terminate, from deep within a macro.

Some ideas:

how about BREAK ?
in a loop: terminate loop

in a macro/function: "return" from that macro/function

on file level: stop processing this file

return and break both implemented. return effectively stops processing of the CMakeLists file at that point. So...

message ("unable to find foo")
return()

should help address this issue
