Unfortunately, the recommendation is to do exactly what you don't want
to do: create a shared target and a static target.
To make this slightly simpler, you can use functions to de-duplicate
the target_* and set_target_properties calls:
function(create_foo_target name type)
add_library(${name} ${type} foo.c foo.h)
set_target_properties(${name} OUTPUT_NAME foo)
endfunction()
create_foo_target(foo_shared SHARED)
create_foo_target(foo_static STATIC)
