I would have to see the code, but it should work.  If you are using 
target_link_libraries with the target name (the correct thing to do), 
you will need to change the target name in that spot as well.

Like this:

add_library(myhelp help.c)
set_target_properties(myhelp  PROPERTIES OUTPUT_NAME Help)
add_executable(foo foo.c)
target_link_libraries(foo myhelp)
