# FindPostgreSQL
# --------------
#
# Find the PostgreSQL installation.
#
# In Windows, we make the assumption that, if the PostgreSQL files are
# installed, the default directory will be C:\Program Files\PostgreSQL.

# This module defines

#
# PostgreSQL_LIBRARIES - the PostgreSQL libraries needed for linking
# PostgreSQL_INCLUDE_DIRS - the directories of the PostgreSQL headers

# ----------------------------------------------------------------------------
# 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 mumber 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:
# "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.
#
# ----------------------------------------------------------------------------
# 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>.
#
