If it were me, I'd add something like...
< IsTfsBuildAgent Condition=" '$( IsTfsBuildAgent)' == ''">no</ IsTfsBuildAgent
>
...
<DefineConstants>
$(DefineConstants);
IsTfsBuildAgent =$(IsTfsBuildAgent);
</DefineConstants>
To your WixProj. Then you should be able to do:
<?if $(var.IsTfsBuildAgent) = "yes" ?>
<?define SourcePath = ".\..\..\binaries" /> <?else ?>
<?define SourcePath = "..\bin\$(var.Configuration)" /> <?endif ?>
Better yet, you could use SourcePath as a MSBuild property and pass it in as a
constant.

Subject: [WiX-users] How to detect an environmental variable's value?
I'm trying to set up a wxs script to handle two different conditions, building
a setup on a normal developer's machine and building a setup on a TFS build
agent. The problem is that the TFS build agent copies the products of a
solution to a binaries folder while a normal developer's build does not. It
occurred to me that the easiest way to handle the problem would be to simply
put an environmental variable on the TFS build agent's machine to identify it
as a TFS build agent and if this environmental variable was found then to use a
different path to find the source. That's the theory, anyway. The practice has
proven to be puzzling since nothing seems to work the way that I'd expected.
My first attempt looked like this:
<?if $(env.IsTfsBuildAgent) = "yes" ?>
<?define SourcePath = ".\..\..\binaries" /> <?else ?>
<?define SourcePath = "..\bin\$(var.Configuration)" /> <?endif ?>
This seemed to work on the TFS build agent but failed on the development
machine because IsTfsBuildAgent is not present. OK, fine, let's try a simple
presence/absence.
<?ifdef $(env.IsTfsBuildAgent) ?>
<?define SourcePath = "..\..\..\binaries" /> <?else ?>
<?define SourcePath = "..\bin\$(var.Configuration)" /> <?endif ?>
I built the setup on my development machine and it worked. Great. Then, to
simulate building on the TFS build agent, I added an environmental variable
IsTfsBuildAgent, set its value to 'yes' and restarted VS with the expectation
that the build would fail with 'cannot find ..\..\..\binaries\whatever' but
instead it compiled a setup program without issue.
Clearly, there's something here that I'm not getting right. Can someone please
explain how to perform logical operations based upon the content of
environmental values?
