and you can adjust OUTPUT names for each unique target:

set_target_properties(${fox_default_libname}-static
                               PROPERTIES OUTPUT_NAME ${fox_default_libname})

set_target_properties(${fox_default_libname}-dynamic
                               PROPERTIES OUTPUT_NAME ${fox_default_libname})

that way you CMake target are unique but they output with the same name.
