At generate-time, definitions are sometimes read from a nearby cmMakefile, making the value directory-specific because they are read once per directory. Often however, the intention is more often to create a 'global' setting, such that the user writes for example: set(CMAKE_IMPORT_LIBRARY_SUFFIX something) once at the top level of their project. Many of these are also set by internal platform files, such as CMAKE_EXTRA_LINK_EXTENSIONS. The set() definitions are not really suitable for 'global' settings because they can be different for each directory, and code consuming the settings must assume they are different for each directory, and read it freshly each time with new allocations. CMake has other variable types which are global in scope, such as global properties, and cache variables. These are less convenient to populate for users, so establish a convention and API using the value as it is at the end of the top-level CMakeLists file.
