[lldb-dev] Is anyone using the gtest Xcode project?

I'm not sure if this is what you meant, but I don't see a lot of value in making an Xcode project that has targets for each of the gtest binaries, and then tries to run the tests.  Seems to me it would be better if the gtest project just invokes whatever mechanism the cmake build would do to run the tests.  That's just another set of things to keep in sync.

It is sufficient to have a target that just does whatever steps cmake/lit do to build the gtests & run them, if that is possible.  I guess if you can't do this without running cmake in the lldb top-level directory that would be a problem.  But it still seems better to me to wire that up, than to have to add tests to both Xcode & cmake.

Schemes exist in both workspaces and projects and are the way to say "do something with some of the stuff referred to by this project/workspace."  So the way to do this formally is to have the gtest scheme build & run the tests from the gtest project.
