Subject: [PATCH] Fix #440: disable tests and examples using `BUILD_TESTING`.

By providing cmake with `BUILD_TESTING=OFF`, no test or example will be built.

`BUILD_TESTING` is `ON` by default, since we are using [`enable_testing`] along with `CTest`.


[`enable_testing`]: https://cmake.org/cmake/help/latest/command/enable_testing.html
