+When libmxl has been built from its source tree but has not been installed into
+a standard prefix, expose its build metadata, source headers, and library
+directory to cgo. For example:
+
+```sh
+export MXL_SOURCE=/Users/jitten/extra/mxl
+export MXL_BUILD="$MXL_SOURCE/build/Darwin-Clang-Release"
+
+export PKG_CONFIG_PATH="$MXL_BUILD${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}"

+export CGO_LDFLAGS="-L$MXL_BUILD/lib"
+
+mkdir -p build
+go build -o build/mxl-player ./cmd/mxl-player
+```
+
+The `CGO_CFLAGS` workaround is needed because the headers are still in the MXL
+source tree. A properly installed MXL SDK should expose them through
+`libmxl.pc` instead.

 Nonstandard loader locations can be supplied explicitly:
 
 ```sh
-export SDL3_LIBRARY=/absolute/path/to/libSDL3.dylib
-export VULKAN_LIBRARY=/absolute/path/to/libvulkan.dylib

+Direct loading of `libMoltenVK.dylib` is the configuration verified to work.
+The Vulkan loader installed through Homebrew did not work in the tested setup,
