Links not included in VSTS

I am building Windows 10 UWP in XAML and C #. I have several extensions installed in VS2017 that are referenced by links from the links section. Since VS2017 Host Agent has no extensions, I had to copy to a local folder and redistribute the extensions with source code. I put this code in CSProj to access extensions by folder.

 <PropertyGroup>
      <SDKReferenceDirectoryRoot>..\SDKs\Microsoft SDKs;
      </SDKReferenceDirectoryRoot>
 </PropertyGroup>

      

        
        
        
      

    

To simulate the process, I will compile using powershell my application using MSBuild 15. When extracting the SDK in powershell compilation, it runs 6 steps, 3 to enumerate and 3 to add the SDK to the project:

ExpandSDKReferences:  Enumerating SDK Reference "Microsoft.VCLibs, 
ersion=14.0" from "C:\Users\myusername\Source\Repos\VSTS\BI Read 
Windows\SDKs\Microsoft SDKs\Windows 
Kits\10\ExtensionSDKs\Microsoft.VCLibs\14.0\".
Enumerating SDK Reference "PDFTron.PDFNetUWPApps, Version=6.5.4.47152" from 
"C:\Users\myusername\Source\Repos\VSTS\BI Read Windows\SDKs\Microsoft 
SDKs\UAP\v0.8.0.0\ExtensionSDKs\PDFTron.PDFNetUWPApps\6.5.4.47152\".
Adding reference "References\CommonConfiguration\x86\pdftron.winmd".
Adding file "Redist\CommonConfiguration\x86\pdftron.dll" from redist folder 
with target path "pdftron.dll".
Enumerating SDK Reference "SQLCipher.UAP.2015, Version=3.4.0" from 
"C:\Users\myusername\Source\Repos\VSTS\BI Read Windows\SDKs\Microsoft 
SDKs\UAP\v0.8.0.0\ExtensionSDKs\SQLCipher.UAP.2015\3.4.0\".
Adding file "Redist\Debug\x86\sqlite3.dll" from redist folder with target 
path "sqlite3.dll".

      

        
        
        
      

    

On the other hand, in a hosted agent in VSTS, it only PROVIDES sdks, but never adds them to the project:

 ExpandSDKReferences:
 Enumerating SDK Reference "Microsoft.VCLibs, Version=14.0" from 
 "C:\a\1\s\SDKs\Microsoft SDKs\Windows 
Kits\10\ExtensionSDKs\Microsoft.VCLibs\14.0\".
Enumerating SDK Reference "PDFTron.PDFNetUWPApps, Version=6.5.4.47152" from 
"C:\a\1\s\SDKs\Microsoft 
SDKs\UAP\v0.8.0.0\ExtensionSDKs\PDFTron.PDFNetUWPApps\6.5.4.47152\".
Enumerating SDK Reference "SQLCipher.UAP.2015, Version=3.4.0" from 
"C:\a\1\s\SDKs\Microsoft 
SDKs\UAP\v0.8.0.0\ExtensionSDKs\SQLCipher.UAP.2015\3.4.0\".

      

        
        
        
      

    

And since it is not added, I have compilation errors. What can happen?

Sincerely.
