Subject: [PATCH] Fix CMake BUILD_FRAMEWORK source include dir and 'make
 install'.

+ The CMakeFiles.txt did not specify a source include directory
  for BUILD_FRAMEWORK builds, causing builds to fail due to
  missing headers when using a build directory other than the
  source directory.
+ The CMakeFiles.txt was missing an install command for
  BUILD_FRAMEWORK builds, so "make install" would fail to actually
  install the framework. This patch specifies the framework install
  destination as CMAKE_INSTALL_PREFIX to match libogg.

Be advised I'm not an experienced CMake user and this is a copypaste
job, so there is almost certainly a cleaner way to do this.
