  +#### Additional Options for Integrators
  +
  +In the event that you are building the BSON C++ library and/or the C++ driver to embed with other components and you wish to avoid the potential for collision with components installed from a standard build or from a distribution package manager, you can make use of the `BSONCXX_OUTPUT_BASENAME` and `MONGOCXX_OUTPUT_BASENAME` options to `cmake`.
  +
  +```sh
  +cmake .. \
  + -DBSONCXX_OUTPUT_BASENAME=custom_bsoncxx \
  + -DMONGOCXX_OUTPUT_BASENAME=custom_mongocxx
  +```
  +
  +The above command would produce libraries named `libcustom_bsoncxx.so` and `libcustom_mongocxx.so` (or with the extension appropriate for the build platform). Those libraries could be placed in a standard system directory or in an alternate location and could be linked to by specifying something like `-lcustom_mongocxx -lcustom_bsoncxx` on the linker command line (possibly adjusting the specific flags to those required by your linker).

  ### Step 6: Test your installation
