# 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>.
|
|
#
