travis build fails running msbuild due to MSB4019 - msbuild

Question

I am trying to build automatically a golang project in a windows environment with travis and to package the .exe making use of msbuild and wix.
The very same configuration works with Github actions and therefore I believe that both the .wixproj and the wxs are correct and there is some issue with the configuration of msbuild in the travis installation, but I have no more clues.
Possibly the msbuild installed by travis does not include the required wix toolset, I tried to install them, however while creating the package the error persist
The error
C:\Users\travis\gopath\src\github.com\gallo-cedrone\nri-elasticsearch\pkg\windows\nri-amd64-installer\nri-installer.wixproj" (default target) (1) ->
C:\Users\travis\gopath\src\github.com\gallo-cedrone\nri-elasticsearch\pkg\windows\nri-amd64-installer\nri-installer.wixproj(34,5):

I found a solution thanks to enter link description here
Basically I was installing the wixtools, however the installation folder was not the expected one by vs2017.
It can be fixed simply by changing:
<Import Project="$(WixTargetsPath)" />
with:
<Import Project="$(WixTargetsPath)" Condition=" '$(WixTargetsPath)' != '' " />
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\WiX\v3.x\Wix.targets" Condition=" '$(WixTargetsPath)' == '' AND Exists('$(MSBuildExtensionsPath32)\Microsoft\WiX\v3.x\Wix.targets') " />
and removing the WixTargetsPath clouses contitions.
