This shouldn’t be a problem because:

--8<---------------cut here---------------start------------->8---
$ pkg-config OpenEXR --cflags
-pthread -I/gnu/store/bnp4nsy7v4lzw562k4v7w34jdg8vkc3s-openexr-2.2.0/include/OpenEXR -I/gnu/store/6ih7f5cq1amgh134f75xw2sxk39p9gi7-ilmbase-2.2.0/include/OpenEXR 
--8<---------------cut here---------------end--------------->8---

My guess is that Vigra doesn’t use pkg-config, and thus doesn’t get the
right -I flags.

Is that a correct guess?  :-)
