ADD_TEST() expands only the actual COMMAND w.r.t. an executable's
full path but not the COMMAND's arguments. However, you might use
generator expressions for this purpose:

ADD_EXECUTABLE(utest1)
ADD_TEST(NAME utest1
    COMMAND /fully/qualified/path/run_utest
        --report $<TARGET_FILE:utest1>)

'hope that helps.
