Good idea. This may lead to what I'm looking for. My svn_revision.cmake
script now looks like this:

find_package(Subversion)
if(Subversion_FOUND)
        Subversion_WC_INFO(${ER_SOURCE_DIR} ER)
        set(REVISION ${ER_WC_REVISION})
        configure_file(${ER_SOURCE_DIR}/scripts/version.sh.in
${ER_SOURCE_DIR}/scripts/version.sh @ONLY)
endif(Subversion_FOUND)

It is invoked in CMakeLists.txt with "install(SCRIPT svn_revision.cmake)".
The only problem I have now is that ${ER_SOURCE_DIR} is not defined in the
external script. Is there a way to pass arguments to this svn_revision.cmake
script?
