"toFloat.h" file is part of the "ilmbase" library (just like
"half.cpp"), which in turn is indeed a part of the OpenEXR library.
("ilm" is an acronym for "Industrial Light & Magic", the company that
originally developed the OpenEXR file format and still maintains the

What's special about "toFloat.h" (and also "eLut.h") is that these two
files are not part of the library's source file package, but are created
as part of the build process (presumably because their contents are

Make sure that the project conversion from VS2010 to VS2015 has kept the
build dependencies and custom build steps intact; rebuilding the "Half"
project should automatically trigger a rebuild of the "eLut" and
"toFloat" projects first; those projects should in turn cause those
files to be created in the "libraries/ilmbase/Half" directory (unless
the respective file already exists and is up to date), which should be
accompanied by the build log output "Generating <filename>...".
