Summary0015509: CMake needs a generator expression equivalent to TO_NATIVE_PATH.
DescriptionSome commands which accept generator expressions also need native pathes as arguments (typically programs parameters passed to add_custom_command on Windows) and the conversion can't be done with the file(TO_NATIVE_PATH ...) command since the generator expression hasn't been evaluated yet.

I have read the CONTRIBUTING.rst (but am not interested in joining the mailing list, thank you), so feel free to use the trivial attached patch as you see fit (it may need to be updated in light of whatever will be done in response to http://public.kitware.com/Bug/view.php?id=5939 [^]).

As discussed in 0005939:0036429, 0005939:0036437, and 0005939:0036440, the concept of a TO_NATIVE_PATH is ill-defined because we don't know what "native" is targeting. Even ConvertToOutputPath may need to be refactored, so I'm hesitant to expose it publicly through any more interfaces than it already is.

Instead some set of well-defined conversions needs to be enumerated. For the purposes of this issue we need to come up with a different name for the proposed generator expression and define precise behavior for it. In particular, it should be defined for use in shell commands with add_custom_command.

That's fine with me. I don't mind waiting (I'm already building CMake from the source anyway) and the patch is archived in case other people are looking for the feature right now.

Once you find an acceptable solution to 0005939 (no opinion, I'm not affected) it should still be trivial to expose the same feature(s) as a generator expression with an appropriate name where it matters.
