[Bf-committers] WITH_OPENEXR required in file that defines it afterwards?

[Ton Roosendaal]

Hi Miguel,

Thanks for the note; CMake is a little bit of an orphan, it gets  
maintained less often than scons & make (default always updated) or  
MSVC (usually updated within a day). There are a couple of developers  
here who tackle cmake regularly though, I'm sure they'll check on this  
openexr issue. :)
