Yes, that's what I meant. Sorry if my previous post wasn't clear enough.

I want the install to fail if the file that is trying to write to is
read-only. This is to prevent the developer from overwriting the file,
if it's not checked out.

I'm using CMake 2.6.4, generating projects for Visual Studio 2005.

Thanks,
Daniel
