     Since I touch this problem several months ago, so I did some test
using the 3.2svn, the reason why uninstalled build 'cmake not work lies in

set(LLVM_INSTALL_PREFIX @LLVM_INSTALL_PREFIX@)
set(LLVM_INCLUDE_DIRS ${LLVM_INSTALL_PREFIX}/include)
set(LLVM_LIBRARY_DIRS ${LLVM_INSTALL_PREFIX}/lib)

LLVM_INCLUDE_DIRS and LLVM_LIBRARY_DIRS points to the user specified or
install tree location, but for uninstalled version, they are non-exist
yet(because not run make install), so set CMAKE_PREFIX_PATH to
builddir\share\llvm\cmake
and then do things as described in http://llvm.org/docs/CMake.html using
find_package(LLVM) and then

include_directories( ${LLVM_INCLUDE_DIRS} )
link_directories( ${LLVM_LIBRARY_DIRS} )

will cause the problem, the directory are not present for the built but
uninstalled source tree.

*hi,Óscar:*
*
*
*so following patch should address both the relocation problem and
uninstall tree problem, not fully tested just for discussion.*

What about LLVM_TOOLS_BINARY_DIR ?

Have you checked that CMAKE_CURRENT_LIST_FILE is available for CMake
2.8.0 ?

Once you address the two questions above, please upload the patch to the
bugzilla ticket you opened for this bug. Thanks!
