We didn't use the latest version, but a compatible version, which is established by raylib-config-version.cmake.

It's ok to have a minimal version, so revert b7c0d5b6dd.

* Always use latest raylib version

Using new file I/O ABI

Note that emscripten upstream branch implements the new asyncify implementation, expected to be faster than emterpreter one.

Examples categories are independent from the module they use, despite in some cases module name matches category name.

Tested on Raspberry Pi... Just note that platform is very limited by GPU...
