Great, I'm glad you found the solution.  Thanks for reporting back.

The command documentation:

 http://www.cmake.org/cmake/help/v2.8.11/cmake.html#command:enable_language

includes the phrase

 "the language enabled can only be used in the calling project or its
  subdirectories"

However, it is not clear that "used" includes transitive link dependencies.
I've updated the documentation to state that explicitly:

 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=b3b57e7a
 "Furthermore, it must be called in the highest directory common to "
 "all targets using the named language directly for compiling sources "
 "or indirectly through link dependencies.  "
 "It is simplest to enable all needed languages in the top-level "
 "directory of a project."
