Comment 1 for bug 966999

Probably, ZorbaUse.cmake should call CONFIGURE_FILE() twice for ExternalModuleConfig.cmake.in - once with values appropriate for loading from the build directory, once with values appropriate for loading from the install directory. However, this is fairly difficult since the relative paths may change radically. See Zorba's own config/CMakeLists.txt and config/ZorbaConfig.cmake.in; it's not a very pretty setup.
