Same source, all that, just want a static and shared version both. Easy to do?

Yes, it's moderately easy. Just use two "add_library" commands:

add_library(MyLib SHARED source1.c source2.c)
add_library(MyLibStatic STATIC source1.c source2.c)

Even if you have many source files, you would place the list of sources in a cmake variable, so it's still easy to do.

On Windows you should probably give each library a different name, since there is a ".lib" file for both shared and static. But on Linux and Mac you can even give both libraries the same name (e.g. libMyLib.a and libMyLib.so):

set_target_properties(MyLibStatic PROPERTIES OUTPUT_NAME MyLib)

But I don't recommend giving both the static and dynamic versions of the library the same name. I prefer to use different names because that makes it easier to choose static vs. dynamic linkage on the compile line for tools that link to the library. Usually I choose names like libMyLib.so (shared) and libMyLib_static.a (static). (Those would be the names on linux.)
