When building with OTK_FETCH_CONTENT=OFF, I hit the same issue that seems to have been hit before where the /EHsc flag, which comes from OpenEXR, is confusing NVCC. Spitting out the following error,

nvcc fatal : A single input file is required for a non-link phase when an outputfile is specified
I noticed there was some logic already written to fix this, so I have simply moved some conditions around so that this gets run regardless of if OTK_FETCH_CONTENT is on or off.
