Hi Charles

Being the guy behind proj4-cmake old repository I supect to be also the guy
who wrote this warning.
If a remember well is due to the fact that nad2nad and nad2bin include
"project.h" and not "proj_api.h". So as on windows dll only include
(export) symbol defined in proj_api.h ( more precisely in proj.def) I was
thinking that when you include "project.h" it's better to link to static
lib in order to have all symbol defined.

I'm note 100% of this fact and I could be wrong but I think it was the
explanation of this warning.  Looking deeper in the code it seems that
nad2bin only use struct defined in project.h and not function so it could
