What does everyone else think?
Well - Code::Blocks is used with literally each and every SDK you can think of, including MS Windows/Platform SDK (different versions, ~500MB each), Direct/X SDK (different versions, around 300MB each), several Open Source libraries (each around at least 10-15MB), including QT (different versions, around 200 MB each) and so on.
Not to forget that some SDK's would depend on the compiler you are using and thus require different libraries... than the platform comes into play (32bit / 64 bit) and so on and so on...
There is
no minimal set that would make developers more happy. So your request is
impossible to do. Sorry.
