'WebGLInput' could not be found in the namespace 'UnityEngine' (Linux Command Line Build)

Hi

Using the editor and CMD on windows, I get a build with no problems, but through the command line on Linux, I get an error.

this error not from the plugins. UnityEngine.WebGLInput is supported by Unity.

Yo! Just got similar problem on MacOS. The problem is in BuildPipeline and scripting symbols. It says:

Note: Be aware that changes to scripting symbols only take effect at the next domain reload, when scripts are recompiled. It also means that the built-in scripting symbols defined for the current active target platform (such as UNITY_STANDALONE_WIN, or UNITY_ANDROID) remain in place even if you try to build for a different target platform, which can result in the wrong code being compiled into your build.

So the solution I've come with is here (you can find my code in the end of the thread): https://forum.unity.com/threads/how-does-domain-reloading-work-when-you-call-switcheditorplatform-within-a-build-script.1278152/
