GTSAM_SINGLE_TEST_EXE option causes compile errors about gtsam

@jlblancoc I think the problem is with MSBuild. Could you test locally with MSBuild instead of VS?

#121

[ProfFan]

@jlblancoc Do we still have this issue? I think you added AppVeyor CI for Win32 platforms...

[jlblancoc]

Yes, but it failed for a weird reason that couldn't replicate locally in MSVC. The error message is:

-- Configuring done
-- Generating done
-- Build files have been written to: C:/projects/gtsam/build
The solution file has two projects named "gtsam_examples".

and I got stuck there so...

Apparently, it has nothing to do with the issue in this thread.

@ProfFan : thanks for the pointer. Using msbuild it fails, but invoking cmake --build . it works (however it internally invokes cl!)

dotnet/msbuild#3019

Is this still an issue?

[varunagrawal]

This is still an issue. There is name-clashing of global variables and functions happening when we merge various test files.

[varunagrawal]

So after some consideration, this issue can be easily solved if we update the namespaces of each of the test files. This is an easy thing to do, but requires a lot of legwork to check and run the tests.
