Looks to me like a bug in the OpenEXR package:

$ apt install libopenexr-dev
$ pkg-config --cflags OpenEXR
Package openjph was not found in the pkg-config search path.
Perhaps you should add the directory containing `openjph.pc'
to the PKG_CONFIG_PATH environment variable
Package 'openjph', required by 'OpenEXR', not found

Installing libopenjph-dev fixes the problem:

$ pkg-config --cflags OpenEXR
-I/usr/include/OpenEXR -pthread -I/usr/include/Imath -D_FILE_OFFSET_BITS=64

As a result, /usr/include/OpenEXR is not added to the include paths for the 
exactimage build. And this will then break the build when it tries to include 
ImfIO.h (/usr/include/OpenEXRImfIO.h)

Regards,
