 FindPostgreSQL
 --------------

 Find the PostgreSQL installation.

 IMPORTED Targets
 ^^^^^^^^^^^^^^^^

 This module defines :prop_tgt:`IMPORTED` target ``PostgreSQL::PostgreSQL``
 if PostgreSQL has been found.

 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
 #]=======================================================================]

 # ----------------------------------------------------------------------------
 # 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>.
 #
