Error CS0234 The type or namespace name 'SharePoint' does not exist in VS2017

Hi Mr. Steinhauser! I am trying to build SPCAMLQueryHelperOnline with Visual Studio 2017. The errors displayed are:

Severity	Code	Description	Project	File	Line	Suppression State
Error	CS0234	The type or namespace name 'SharePoint' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)	SPCAMLQueryHelperOnline	C:\msys64\home\djpeter1\SPCAMLQueryHelperOnline\SPCAMLQueryHelperOnline\classes\WebServiceWork.cs	1	Active
Warning		Could not resolve this reference. Could not locate the assembly "Microsoft.SharePoint.Client". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.	SPCAMLQueryHelperOnline

Warning		Could not resolve this reference. Could not locate the assembly "Microsoft.SharePoint.Client.Runtime". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.	SPCAMLQueryHelperOnline			

Any suggestions for what VS components are missing? I am attempting to run from a client, not a SharePoint server. Thanks for your time!
