build with openexr 3

[pgajdos]

Hi,

could you please consider building against OpenEXR 3? Patches to fix cmake rules exists already, e. g.:
https://src.fedoraproject.org/rpms/vigra/blob/rawhide/f/vigra-openexr3.patch

Thanks

CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

If desperate you could try this yourself https://ask.fedoraproject.org/t/vigra-update/18853 post-2 says:

sudo dnf -y install fedpkg
fedpkg clone --anonymous vigra
cd vigra
fedpkg prep
This will create a vigra-1.11.1 sub-directory which will have all of the Fedora patches applied.
