Fix:

if(CMAKE_MATCH_1)
    set (Unwind_VERSION
            ${Unwind_VERSION_MAJOR}.${Unwind_VERSION_MINOR}.${Unwind_VERSION_PATCH})
    set (Unwind_VERSION_COMPONENTS 3)
else()
    set (Unwind_VERSION
            ${Unwind_VERSION_MAJOR}.${Unwind_VERSION_MINOR})
    set (Unwind_VERSION_COMPONENTS 2)
endif()
