Where does the $(WixTargetsPath) property get set for this .wixproj file?-CodePudding

I am new to project files and was doing some investigating today to try and understand the .wixproj file that was automatically generated using VS2019 WiX project template. I was able to understand most of it, but I am stuck on one small question. Where does the $(WixTargetsPath) property get set? At this point I have probably wasted a lot of time trying to figure this out for no reason, but I am just so curious now! I read up on all the different ways properties can get set in a proj file but I was not able to find the variable definition anywhere. Here is my .wixproj file:

  <Target Name="EnsureWixToolsetInstalled" Condition=" '$(WixTargetsImported)' != 'true' ">

I checked the environment variable's but did not find anything. I read up on .props files, but have no idea where a wix.props file would be included. It builds with msbuild so I know it is set, but aside from the wix installer modifying msbuild.exe to include additional default properties I have no idea where this property is set.

CodePudding user response：

It doesn't. The

Condition=" '$(WixTargetsPath)' != '' "

ensures the Import is attempted only if it is set.

That line exists if you want to point to a wix.targets file that isn't in the MSBuildExtensionsPath32 path used in the next line.
