## Add Subproject
A package can include your project in a subdirectory, and then use `add_directory` on the subdirectory. This useful for header-only and quick-to-compile libraries. Note that the install commands may interfere with the parent project, so you can add `EXCLUDE_FROM_ALL` to the `add_subdirectory` command; the targets you explicitly use will still be built.

In order to support this as a library author, make sure you use `CMAKE_CURRENT_SOURCE_DIR` instead of `PROJECT_SOURCE_DIR` (and likewise for other variables, like binary dirs). You can check `CMAKE_PROJECT_NAME STREQUAL PROJECT_NAME` to only add options or defaults that make sense if this is a project.
