+mkdir build
+cd build
+cmake -D CMAKE_TOOLCHAIN_FILE=/home/chee/projects/Arduino-CMake-Toolchain/Arduino-toolchain.cmake
+-D CMAKE_EXPORT_COMPILE_COMMANDS=1  ..
+ln build/compile_commands.json ..
+```
+
+then uncomment the pygamer lines in the generated `BoardOptions.cmake`, then run
+the cmake command again and run `make` to build it.
+
+## watching
+
+if you keep this running, emacs will know about the new includes when you do an lsp-workspace-restart
