Building OpenEXR from master (a0e84f62def6276f38e518a2724d9f7ac4daa9ad), the pkg-config looks correct:

[openexr (master)]$ mkdir build
[openexr (master)]$ cd build
[openexr/build (master)]$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr && make -j8
[openexr/build (master)]$ cat OpenEXR/OpenEXR.pc

https://github.com/AcademySoftwareFoundation/openexr/issues/595 looks related but it says "fix broken CMake files". And is in 2.4.1 and on master but not in 2.4.0. Not sure what is going on exactly.
