Subject: [PATCH] Add support for CMake find_package()

Added export configuration for UnitTest++ target and installed the export and config file in libs/cmake/UnitTest++.
Added basic UnitTest++Config.cmake file which includes exported targets file and sets UTPP_INCLUDE_DIRS to the install location of the includes directory, this allows UnitTest++ to be used as a normal target in your own CMakeLists.txt file.

e.g.:

    find_package(UnitTest++ REQUIRED NO_MODULE)
    add_executable(foo ...)
    include_directories(${UTPP_INCLUDE_DIRS})
    target_link_libraries(foo UnitTest++)

which will ensure the library and installed headers paths are set up correctly for your own target.
