Of course right now only Visual Studio and XCode support the toolset
parameter (according to the docs). These both happen to be global
generators. However, I was thinking of a case in the future where
Eclipse CDT4 or Code Blocks may support toolsets. Would these be
implemented through global generators anyway? Does it make sense for
extra generators to support toolset? Some educational explanation here
for my benefit would be appreciated.
