| # - Find Cyrus SASL (sasl.h, libsasl2.so) |
| # |
| # This module defines |
| # CYRUS_SASL_INCLUDE_DIR, directory containing headers |
| # CYRUS_SASL_SHARED_LIB, path to libsasl2.so |
| # CYRUS_SASL_LIB_DEPS other libraries that SASL depends on |
| # CYRUS_SASL_FOUND, whether Cyrus SASL and its plugins have been found |
| # |
| # N.B: we do _not_ include sasl in the toolchain, 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 toolchain) 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. |
