Thanks for the feedback. I do need sanity checking here :).

Your message seems to be concerned with use-cases mine was not concerned 
with though (such as multiple entry points). My proposal is concerned with 
writing cross-platform cmake code. So 

 add_executable(myappname ...)

instead of 

 if (ANDROID)
   add_library(myappname ...)
 elif(...)
   ...
 else()
   add_executable(myappname)
 endif()

In that scenario, I have an application (one entry point) which I want to 
build for multiple platforms.

Thanks,

Steve.
