[Openexr-devel] IlmImf lib not built (VS2017/cmake)

Robin Rowe

Building latest on VS2017. Everything seems to build except IlmImf lib.
There's no error message in the build output, except that it objects
that the IlmImf lib doesn't exist:

33>LINK : fatal error LNK1104: cannot open file
'..\IlmImf\Debug\IlmImf-2_2.lib'

It's true that's not built, however I can't see why not. I'm using
github DownloadProject to automatically download the OpenEXR sources,
which seems to work fine. My CMake file below. Ideas?
