[CMake] [resolved] Debug build compiles and links, but Release build fails to link?

Just to comment here: The behaviour I saw was _identical_ on Linux and  
Windows (you seem to think otherwise, I just thought I'd make that  
clear). In other words, on both platforms, the code compiled and  
linked in debug mode, and in release (or at least, when NDEBUG was  
defined) the linker complained that those two methods, which were  
defined as inline but not declared as such, were not found.

I haven't experimented with other compilation options (I didn't even  
check to see whether defining NDEBUG in a debug build would reproduce  
the behaviour, and I don't have the code with me right now). But  
anyways, the problem is solved, and I won't make that mistake anymore  
(see below). And since this is a build tool's mailing list, and not a  
compiler mailing list, I think that's the important thing. I may  
experiment more later.

Indeed it was, and indeed I have.

Thanks,
