All of these are simply symbols that the linker cannot find (but they
had been declared in some header). Either the corresponding source was
not compiled, or failing to link against a library. In this particular
case, I see that I can get past this using:

diff --git a/mobile/components/CMakeLists.txt
b/mobile/components/CMakeLists.txt index e09326a..d3ba32f 100644
--- a/mobile/components/CMakeLists.txt
+++ b/mobile/components/CMakeLists.txt
@@ -30,6 +30,7 @@ target_link_libraries(okularplugin
         Qt5::Xml
         Qt5::Svg
         okularcore
+        okularpart
         KF5::KDELibs4Support
         )

Not so sure, whether this is the correct fix, though. My understanding
is that the definitions are in the _generated_ conf/settings.cpp, and
that 
   kconfig_add_kcfg_files(okular_SRCS
       ${CMAKE_SOURCE_DIR}/conf/settings.kcfgc )
_should_ have added it. However, I've never dealt with the kconfig
compiler myself.

Also, this does not yet get the build done. Another missing symbol,
later... Anyway, perhaps some of this helps you find a solution.

Regards
Thomas
