This patch (and 05/11, SDK_LAYERS_EXCLUDE*) worry me a little in that they 
have the potential to break the resulting eSDK or make it behave in a manner 
that is different from the build system that produced it. Having said that 
it's going to be reasonably clear to the user what's happened, assuming they 
remember they set these variables and in any case I don't expect these are 
going to be set by many people. Accordingly I won't object to these patches, 
but could you please add a warning about this issue to the commit message for 
both? We'd also better ensure they get documented with similar warnings.

Apart from that I'd like to see a different name for the variable here - we 
don't use the prefix ESDK_ anywhere else, so perhaps SDK_CONF_MANIFEST_EXCLUDE 
?

Cheers,
Paul
