Specify modules to look for OpenEXR when CMake is used, as we may have CMake config files instead of pkg-config files that result from building OpenEXR, which may be built with CMake which is typically the case on Visual Studio builds. In this case, Meson does seem to find the 'OpenEXR' package with CMake after trying pkg-config, but does not consider it enough without the 'modules:' argument.
