- Remove kcalendarcore and kcontacts from BUILD_DEPENDS and
RUN_DEPENDS. A new port of KF5Akonadi is required in order to link
against these.
- Add CONFIGURE_ARG to skip finding KF5Akonadi.
- Add math/imath to LIB_DEPENDS and Imath-3_1 to WANTLIB.
- Set OpenEXR_FOUND in CMakeLists.txt patch to help with linking against
imath.
