Subject: [PATCH] build: as submodule, cancel `add_test()` (#160)

if we use `etcd-cpp-apiv3` as submodule, we don't need to test `etcd-cpp-apiv3`.
in `CMakeLists.txt`
```
enable_testing()
add_subdirectory(src)
add_subdirectory(tst)
```
this code force to set `add_test()` and maybe make the project failed to `unit tests`.
