Hello,

I saw your commit r221411 (Make it easier to build against a pre-built
Clang package with CMake, 2014-11-05).

The documentation of the export command:

 http://www.cmake.org/cmake/help/v3.0/command/export.html

contains this paragraph:

"The file created by this command is specific to the build tree and
should never be installed. See the install(EXPORT) command to export
targets from an installation tree."

Consider using that command.

The cmake-packages manual describes how to use the find_dependency macro
to find dependencies. It is a simple macro and can be backported and
used with older CMake if you can't rely on CMake 3.0.

Thanks,

Steve.
