error: unknown type name 'RwReg'

Hi, I fail to run this on MacOS

• Using cmake from homebrew
• Using emscripten from github
• Using FastLED from github

Error message:

Thankful for any assistance.

You have to use my patched version of FastLed: https://github.com/jandelgado/FastLED/tree/82ec8ba5046ae36bff3b82e9c2efdf4caa4559d8 since my PR is not yet merged: https://github.com/FastLED/FastLED/pull/1158
