llvm dev - Jan 2016 - cmake: program name prefix?

Thanks all for replies.

Chris' reply assumes that the prefix string must be a target triple and thus
should be parsed by tools.  It might be easier to do a halfway step: provide a
PROGRAM_PREFIX option, but not require that the prefix string correspond to a
target triple descriptor string.  This sounds like it would also satisfy
Krzysztof's use case (as "hexagon-" is not a target triple
specifier anyway) and it would satisfy mine too.

I am curious, would the project be interested in such a half-way patch?

Given that there are two use cases already, I'd suggest that there is 
indeed an interest.  Those who don't need this will probably not be 
actively interested, so as long as nobody objects, I'd say, let's do it.

To recap: the proposal is to add a cmake argument PROGRAM_PREFIX=xyz, 
whose only function would be to prepend "xyz" to the names of all 
binaries installed through the "install" target.  The default would be
an empty string (or an unset value), so those who don't specify it won't
see any change.

Are there any objections to this?

Not from here.  FWIW we also rename the build products, currently in a
separate packaging step that we do anyway.  So, we're unlikely to take
advantage of the feature ourselves, but it's certainly a reasonable thing
to want.
