# does not relate these two things, i.e. if the environment variable is set,
# CMake does not populate the cache variable in a corresponding manner. Some
# package systems, such as Homebrew, set the environment variable but not the
# cache variable. Furthermore, the environment variable follows the system path
# separator, such as ':' on POSIX and ';' on Windows, but the cache variable
# follows CMake's array behavior, i.e. always ';' for a separator.
