+## cmake-test
+
+This directory can be built as a separate project to test/verify a ggml
+installation.
+
+### Usage
+The following will configure, build, and install ggml using two different
+configurations. One will use dynamically linked backends (GGML_BACKEND_DL=ON)
+and one without.
+
+Configuring, build, and install ggml:
+```console
+./build-install.sh
+```
+
+Build this project twice using the installations created above:
+```console
+./build.sh
+```
