What makes you think there is a problem in Tests/CMakeLists.txt?

What files are generated in the build tree?

The toplevel makefile is created here:
void cmGlobalUnixMakefileGenerator3::WriteMainCMakefile()

But there are lots of other files that get created.

One thing you could try is to use the bootstrapped cmake to configure a 
more simple project.  Something like:

project(foo)
add_library(foo foo.c)
foo.c can be an empty file.

Does the bootstrapped cmake work on that project?

I would not worry about that yet.
