Result Variables ^^^^^^^^^^^^^^^^ This module will set the following variables in your project: ``PostgreSQL_FOUND`` True if PostgreSQL is found. ``PostgreSQL_LIBRARIES`` the PostgreSQL libraries needed for linking ``PostgreSQL_INCLUDE_DIRS`` the directories of the PostgreSQL headers ``PostgreSQL_LIBRARY_DIRS`` the link directories for PostgreSQL libraries ``PostgreSQL_VERSION_STRING`` the version of PostgreSQL found ``PostgreSQL_TYPE_INCLUDE_DIR`` the directories of the PostgreSQL server headers Components ^^^^^^^^^^ This module contains additional ``Server`` component, that forcibly checks for the presence of server headers. Note that ``PostgreSQL_TYPE_INCLUDE_DIR`` is set regardless of the presence of the ``Server`` component in find_package call.#]=======================================================================]# ----------------------------------------------------------------------------# History:# This module is derived from the module originally found in the VTK source tree.## ----------------------------------------------------------------------------# Note:# PostgreSQL_ADDITIONAL_VERSIONS is a variable that can be used to set the# version number of the implementation of PostgreSQL.# In Windows the default installation of PostgreSQL uses that as part of the path.# E.g C:\Program Files\PostgreSQL\8.4.# Currently, the following version numbers are known to this module:# "11" "10" "9.6" "9.5" "9.4" "9.3" "9.2" "9.1" "9.0" "8.4" "8.3" "8.2" "8.1" "8.0"## To use this variable just do something like this:# set(PostgreSQL_ADDITIONAL_VERSIONS "9.2" "8.4.4")# before calling find_package(PostgreSQL) in your CMakeLists.txt file.# This will mean that the versions you set here will be found first in the order# specified before the default ones are searched.## ----------------------------------------------------------------------------# You may need to manually set:# PostgreSQL_INCLUDE_DIR - the path to where the PostgreSQL include files are.# PostgreSQL_LIBRARY_DIR - The path to where the PostgreSQL library files are.# If FindPostgreSQL.cmake cannot find the include files or the library files.## ----------------------------------------------------------------------------# The following variables are set if PostgreSQL is found:# PostgreSQL_FOUND - Set to true when PostgreSQL is found.# PostgreSQL_INCLUDE_DIRS - Include directories for PostgreSQL# PostgreSQL_LIBRARY_DIRS - Link directories for PostgreSQL libraries# PostgreSQL_LIBRARIES - The PostgreSQL libraries.## The ``PostgreSQL::PostgreSQL`` imported target is also created.## ----------------------------------------------------------------------------# If you have installed PostgreSQL in a non-standard location.# (Please note that in the following comments, it is assumed that <Your Path># points to the root directory of the include directory of PostgreSQL.)# Then you have three options.# 1) After CMake runs, set PostgreSQL_INCLUDE_DIR to <Your Path>/include and# PostgreSQL_LIBRARY_DIR to wherever the library pq (or libpq in windows) is# 2) Use CMAKE_INCLUDE_PATH to set a path to <Your Path>/PostgreSQL<-version>. This will allow find_path()# to locate PostgreSQL_INCLUDE_DIR by utilizing the PATH_SUFFIXES option. e.g. In your CMakeLists.txt file# set(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "<Your Path>/include")# 3) Set an environment variable called ${PostgreSQL_ROOT} that points to the root of where you have# installed PostgreSQL, e.g. <Your Path>.## ----------------------------------------------------------------------------if(CMAKE_VERSION VERSION_GREATER_EQUAL"3.20")include("${CMAKE_ROOT}/Modules/FindPostgreSQL.cmake")return()endif()cmake_policy(PUSH)cmake_policy(SET CMP0057 NEW)# if IN_LISTif(POLICY CMP0159)cmake_policy(SET CMP0159 NEW)endif()set(PostgreSQL_INCLUDE_PATH_DESCRIPTION "top-level directory containing the PostgreSQL include directories.
