Hi Ben,

Thanks for taking the time to look at this.

Okay. So that means the files are being generated during the build but
not installed for some reason

Yes those will definitely existing if you build LLVM using the CMake
build system but since LLVM 3.5 the Autoconf/Makefile build system
also generates and installs CMake files into the LLVM install tree.
Perhaps you could do a clean build of LLVM using the Autoconf/Makefile
build system outside of your chroot to see if there's something about
your chroot environment causing the problem?

Okay and those existed after a build without you needing to run
``make`` inside the ``cmake/modules/`` directory in the build tree?

Okay so I am right in understanding that after completing a build...

- When you ran ``make install`` from the root of the build tree the
CMake files are not installed into ``share/llvm/cmake``.
- After trying the above you ran ``make install`` in the
``cmake/modules`` directory in the build tree and the CMake files were
installed to ``share/llvm/cmake``

?

I don't quite understand what you mean. Could you explain that again?
Are you saying that you ran ``make install`` again in the root of the
build tree and additional
libraries were installed?

If so that doesn't good. Sounds like a bug.

@Eric : Have you ever seen anything like this before?

Thanks,
Dan.
