May be you can just generate 2 differents executables from the same source:
yourprog-emul
yourprog-real
This can be done easily using something like:
add_executable(yourprog-emul ${SOURCE})
target_link_libraries(yourprog-emul ${LIBS})
set_target_properties(yourprog-emul PROPERTIES COMPILE_FLAGS
"-DEMULATION_MODE=ON")
add_executable(yourprog-real ${SOURCE})
target_link_libraries(yourprog-real ${LIBS})
set_target_properties(yourprog-real PROPERTIES COMPILE_FLAGS
"-DEMULATION_MODE=OFF")
then you install both target using COMPONENT
install(target yourprog-real DESTINATION <dest>
COMPONENT RealMode)
install(target yourprog-emul DESTINATION <dest>
COMPONENT EmulMode)
Since you are using NSIS, you should be able to select component
from the NSIS installer at install time, see:
