What's immature is the documentation, mostly because it tries to go
beyond what's really required. But on the other hand anyone who knows
how to use cmake shouldn't need the documentation, except perhaps for
the part that explains some variables specific to the LLVM build. (That
part is complete). A TODO on the web page doesn't mean that the feature
is missing. Cross compiling, for instance, should work (it worked when I
tried months ago) but it is not documented. You need to read the cmake
documentation for learning how to cross-compile.

Right now the only fundamental thing missing on the cmake build spec is
running the tests.

Thanks! Fixed.

BTW, bug reports are welcome.
