+If using a version prior to 9.3.0, the `LLHTTP_BUILD_SHARED_LIBS` and `LLHTTP_BUILD_STATIC_LIBS` options are known as `BUILD_SHARED_LIBS` and `BUILD_STATIC_LIBS` and should be used instead.
+
 _Note that using the git repo directly (e.g., via a git repo url and tag) will not work with FetchContent_Declare because [CMakeLists.txt](./CMakeLists.txt) requires string replacements (e.g., `_RELEASE_`) before it will build._
