How to force msbuild to ignore warning MSB8012

Question

I know this question was discussed hundreds of times, but I still cannot find solution. Maybe something was changed in msbuild and I am not aware. The problem is that I get the following warning

warning MSB8012: TargetPath(d:\src\output\Techd.dll) does not match the Linker's OutputFile 
property value (d:\src\output\Debug32\bin\Techd.dll). This may cause your project to build 
incorrectly. To correct this, please make sure that $(OutDir), $(TargetName) and
$(TargetExt) property values match the value specified in %(Link.OutputFile).

I change the outdir by property

msbuild.wxw /p:OutDir="my_out_dir"

I cannot change projects properties and I am not allowed to modify msbuild target files (Microsoft.CppBuild.targets). So don't have any idea hot to force msbuild to ignore this warning or to ignore the $OutDir variable's change.

You should be able to silence MSBuild warnings using a command line parameter:

msbuild.exe /nowarn:MSB8012

In an upcoming update to MSBuild/VS2017 (15.3), you can specify properties to control MSBuild warnings in project files as a property, so that it also affects builds in VS:

<MSBuildWarningsAsMessages>MSB8012</MSBuildWarningsAsMessages>

For current msbuild version /nowarn works only for compile warnings, MSB8012 is msbuild warning. – Gayane May 10 '17 at 11:34
Which version are you using? The current (15/15.1) version should be able to use `/nowarn` as command line argument to suppress msbuild warnings (different than compile warnings) – Martin Ullrich May 10 '17 at 12:07
which is just a short form for `/warnasmessage:` – Martin Ullrich May 10 '17 at 12:08
Our version is older. 14.0 We use VS 2015 – Gayane May 10 '17 at 12:27

Is it possible to install latest version of MSBuild and use it with vs2015? – Gayane May 10 '17 at 12:53

Not really. Yes those suppress options are new to vs2017/msbuild 15 – Martin Ullrich May 10 '17 at 12:55

That is why I am lost. Really don't know how to handle this problem – Gayane May 10 '17 at 12:58
