# Check to see whether a particular set of modules exists. Similar
# to PKG_CHECK_MODULES(), but does not set variables or print errors.
#
#
# Similar to PKG_CHECK_MODULES, make sure that the first instance of
# this or PKG_CHECK_MODULES is called, or make sure to call
# PKG_CHECK_EXISTS manually
# Please remember that m4 expands AC_REQUIRE([PKG_PROG_PKG_CONFIG])
# only at the first occurence in configure.ac, so if the first place
# it's called might be skipped (such as if it is within an "if", you
# have to call PKG_CHECK_EXISTS manually
