You seem to not be linking a library that is needed. A quick google search indicates that you need to link to the IOKit framework for at least some of these symbols.

I recommend you look at the Using Libraries page on Firebreath.org for information on how to link to a Mac framework. It'll look something like this:

find_library(FRAMEWORK_IOKIT IOKit)
target_link_libraries(${PROJECT_NAME} ${FRAMEWORK_IOKIT})

This needs to go in Mac/projectDef.cmake somewhere after your add_mac_plugin call.
