sranipal plugin problem in unreal engine 4.24.2

[bipul mohanto]

Hi! I am following @MariosBikos VRS tutorial on unreal 4.24.2 source code version. 

• I have already steamvr, sranipal runtime, and calibration done. After building the unreal source code I am creating a new project: Games >> Virtual Reality>> Blueprint (cannot see the C++ option).
• I am pasting the sranipal SDK v1.3.6.8 in the project folder under Plugins/SRanipal
• Before that, I have modified the  SRanipal.Build.cs

        /*
        PublicIncludePaths.AddRange(
			new string[] {
                Path.GetFullPath(Path.Combine(ModuleDirectory, ".."))+"/SRanipal/Public"
                // ... add public include paths required here ...
			}
            );
				
		
		PrivateIncludePaths.AddRange(
			new string[] {
                ModuleDirectory+"/Private",
                ModuleDirectory+"/Public/Eye",
                ModuleDirectory+"/Public/Lip",
                Path.GetFullPath(Path.Combine(ModuleDirectory, ".."))+"/SRanipalEye/Public",
                Path.GetFullPath(Path.Combine(ModuleDirectory, ".."))+"/SRanipalLip/Public"
                // ... add other private include paths required here ...
            }
            );
			*/
PublicIncludePaths.Add(Path.Combine(ModuleDirectory,"Public/Eye"));
PublicIncludePaths.Add(Path.Combine(ModuleDirectory,"Public/Lip"));

PrivateIncludePaths.Add(Path.Combine(ModuleDirectory,"Private/Eye"));

• However, while in the project, I cannot see the sranipal plugin under edit>> plugin>> project.
• while I am trying to reopen the project, I am getting the following error message and the project fails to reopen:
• 

Could you please assist me in solving the problem to enable eye tracking?

In connection with my question, cannot I build the unreal engine while the sranipal is in the source plugins folder `C:\UnrealEngine\Engine\Plugins`? While I was trying this: the output build messages were with error message:
