From: Manuel Nickschas Date: Wed, 8 Aug 2018 20:22:39 +0000 (+0200) Subject: cmake: Modernize cmake support for LDAP X-Git-Tag: test-travis-01~167 X-Git-Url: https://git.quassel-irc.org/?a=commitdiff_plain;h=bad087a1b604c92c7c0bf3cf818b81d26e15c1c4;hp=53f09c31bd4e59ffc1830660aebb221f52b06a6f;p=quassel.git cmake: Modernize cmake support for LDAP Use a more modern, property-based find script for the LDAP libraries and get rid of the deprecated use of LDAP_LIBRARIES and similar variables in favor of a namespaced Ldap::Ldap target. Set package properties for better diagnostic output at configure time. --- diff --git a/CMakeLists.txt b/CMakeLists.txt index f6b7f65b..e4f5d617 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -312,13 +312,11 @@ if (BUILD_CORE) if (WITH_LDAP) find_package(Ldap QUIET) - if (LDAP_FOUND) - message(STATUS "Enabling LDAP authentication support") - else() - message(STATUS "Disabling LDAP authentication support") - endif() - else() - message(STATUS "Not enabling LDAP authentication support") + set_package_properties(Ldap PROPERTIES TYPE OPTIONAL + URL "http://www.openldap.org/" + DESCRIPTION "LDAP (Lightweight Directory Access Protocol) libraries" + PURPOSE "Enables core user authentication via LDAP" + ) endif() endif() diff --git a/cmake/FindLdap.cmake b/cmake/FindLdap.cmake index 2c96faeb..1d1d1641 100644 --- a/cmake/FindLdap.cmake +++ b/cmake/FindLdap.cmake @@ -1,60 +1,104 @@ -# Copied from https://raw.github.com/facebook/hiphop-php/master/CMake/FindLdap.cmake - -# - Try to find the LDAP client libraries -# Once done this will define +#.rst: +# FindLdap +# -------- +# +# Try to find the LDAP client libraries. +# +# This will define the following variables: +# +# ``Ldap_FOUND`` +# True if libldap is available. +# +# ``Ldap_VERSION`` +# The version of libldap +# +# ``Ldap_INCLUDE_DIRS`` +# This should be passed to target_include_directories() if +# the target is not used for linking +# +# ``Ldap_LIBRARIES`` +# The LDAP libraries (libldap + liblber if available) +# This can be passed to target_link_libraries() instead of +# the ``Ldap::Ldap`` target +# +# If ``Ldap_FOUND`` is TRUE, the following imported target +# will be available: # -# LDAP_FOUND - system has libldap -# LDAP_INCLUDE_DIR - the ldap include directory -# LDAP_LIBRARIES - libldap + liblber (if found) library -# LBER_LIBRARIES - liblber library +# ``Ldap::Ldap`` +# The LDAP library +# +#============================================================================= +# Copyright 2006 Szombathelyi György +# Copyright 2007-2016 Laurent Montel +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions +# are met: +# +# 1.
