Hi, I think, package kdepim-addons needs libkpimaddressbookimportexport-dev as build-dependency.
quote from kdepim-addons-21.08.1/kaddressbook/CMakeLists.txt: add_subdirectory( editorpages ) add_subdirectory( plugins ) if (KPimAddressbookImportExport_FOUND) add_subdirectory( importexportplugins ) else() MESSAGE(STATUS "You need to build kaddressbook first and add install it on distro before building kdepim-addons. Otherwise import/export will be missing in kaddressbook") endif() I think, package kdepim-addons needs libkpimaddressbookimportexport-dev as build-dependency Rico
