             Bug #: 12157
           Summary: llvmconfig.cmake.in make cmake installations not
                    relocatable
           Product: Build scripts

          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: cmake

the installed llvm package is not relocatable and has reference to the source
tree, this problem maybe fixed using dynamic relative path calculations as
follows:

line21:
set(LLVM_TOOLS_BINARY_DIR @LLVM_TOOLS_BINARY_DIR@)

should be replaced to 
set(LLVM_TOOLS_BINARY_DIR ${CMAKE_CURRENT_LIST_DIR}/../../bin)

line 34
set(LLVM_INSTALL_PREFIX @LLVM_INSTALL_PREFIX@)

to:

set(LLVM_INSTALL_PREFIX ${CMAKE_CURRENT_LIST_DIR}/../..)

line 136:

    "@LLVM_SOURCE_DIR@/cmake/modules")
to
    ${LLVM_INSTALL_PREFIX}/share/llvm/cmake)
