TemplateGenerator CMake Install

Since bzr r97, the TemplateGenerator adds an install target to the generated CMakeLists.txt file.
This simplifies copying the new modules into an existing module collection, e.g. where the prebuilt binaries are located.
On Win32, one should set the CMAKE_INSTALL_PREFIX variable to where the binaries have been unzipped, on Linux one usually would use /usr or /usr/local.
