# - Find Cyrus SASL (sasl.h, libsasl2.so)
#
# This module defines
#  CYRUS_SASL_INCLUDE_DIR, directory containing headers
#  CYRUS_SASL_SHARED_LIB, path to Cyrus SASL's shared library
#  CYRUS_SASL_FOUND, whether Cyrus SASL and its plugins have been found
#
# N.B: we do _not_ include sasl in thirdparty, for a fairly subtle reason. The
# TLDR version is that newer versions of cyrus-sasl (>=2.1.26) have a bug fix
# for https://bugzilla.cyrusimap.org/show_bug.cgi?id=3590, but that bug fix
# relied on a change both on the plugin side and on the library side. If you
# then try to run the new version of sasl (e.g from our thirdparty tree) with
# an older version of a plugin (eg from RHEL6 install), you'll get a SASL_NOMECH
# error due to this bug.
#
# In practice, Cyrus-SASL is so commonly used and generally non-ABI-breaking that
# we should be OK to depend on the host installation.

# Note that this is modified from the version that was copied from our
# friends at the Kudu project.  The original version implicitly required
# the Cyrus SASL.  This version will only complain if REQUIRED is added.
