macro(expat_shy_set var default cache type desc)
# Macro expat_shy_set came into life because:
# - Expat was previously using an inconsistent mix of CMake's native set()
# and option() to define public build time options.
# - option() is more friendly than set() with regard to configuring an
# external project that is pulled in by means of add_subdirectory() --
# see comments in issue #597 -- so we wanted to get away from set().
# - option() auto-converts non-bool values to bool when writing to the CMake
# cache, so we needed something that supports non-bool better and hence
# wanted to get away from plain option(), too.
#
# As a result, this function serves as a hybrid between CMake's regular set()
# and option(): from set() it takes support for non-bool types and the function
# name and signature whereas from option() (with policy CMP0077 mode NEW) it
# takes being shy when a value has previously been defined for that variable.
#
# So that resolves all need for set(.. FORCE) when pulling in Expat by means of
# add_subdirectory().
