CMake: builds involving this target will not be correct

[TheAifam5]

Hey!

I'm get an warning when I try to compile it using CMake:
warning: multiple rules generate thirdparty/json-c/json-c.lib. builds involving this target will not be correct; continuing anyway [-w dupbuild=warn]

I think that's because the project does not have switch between static library and dynamic library, and also because of: set_target_properties(json-c-static PROPERTIES OUTPUT_NAME json-c)

Without that set_target_properties I'm don't get any warnings.

Regards,
Mateusz

looks related to #415

On windows you try to set the same name for shared and static libraries using ‚set_target_properties‘. Simple if with NOT (MSVC OR MINGW OR WIN32) etc should be enough.

s/b fixed by merging the changes in #415.
