Here's the order of the "additional dependencies" :
$(ProjectDir)../../../../libs/OpenExr_win32/lib/Debug/Iex.lib
$(ProjectDir)../../../../libs/OpenExr_win32/lib/Debug/Imath.lib
$(ProjectDir)../../../../libs/OpenExr_win32/lib/Debug/IlmThread.lib
$(ProjectDir)../../../../libs/OpenExr_win32/lib/Debug/IlmImf.lib
$(ProjectDir)../../../../libs/OpenExr_win32/lib/Debug/Half.lib
Also I added $(ProjectDir)../../../../libs/OpenExr_win32/lib/Debug/ to the "additionnal library directories"
Well I put the .dll in the build directory... but anyway it doesn't compile since I have this Unresolved external sticking to the linker .
