32 # This module is derived from the module originally found in the VTK source tree.
34 # ----------------------------------------------------------------------------
36 # PostgreSQL_ADDITIONAL_VERSIONS is a variable that can be used to set the
37 # version mumber of the implementation of PostgreSQL.
38 # In Windows the default installation of PostgreSQL uses that as part of the path.
39 # E.g C:\Program Files\PostgreSQL\8.4.
40 # Currently, the following version numbers are known to this module:
41 # "9.1" "9.0" "8.4" "8.3" "8.2" "8.1" "8.0"
43 # To use this variable just do something like this:
44 # set(PostgreSQL_ADDITIONAL_VERSIONS "9.2" "8.4.4")
45 # before calling find_package(PostgreSQL) in your CMakeLists.txt file.
46 # This will mean that the versions you set here will be found first in the order
47 # specified before the default ones are searched.
49 # ----------------------------------------------------------------------------
50 # You may need to manually set:
51 # PostgreSQL_INCLUDE_DIR - the path to where the PostgreSQL include files are.
52 # PostgreSQL_LIBRARY_DIR - The path to where the PostgreSQL library files are.
53 # If FindPostgreSQL.cmake cannot find the include files or the library files.
55 # ----------------------------------------------------------------------------
56 # The following variables are set if PostgreSQL is found:
57 # PostgreSQL_FOUND - Set to true when PostgreSQL is found.
58 # PostgreSQL_INCLUDE_DIRS - Include directories for PostgreSQL
59 # PostgreSQL_LIBRARY_DIRS - Link directories for PostgreSQL libraries
60 # PostgreSQL_LIBRARIES - The PostgreSQL libraries.
62 # ----------------------------------------------------------------------------
63 # If you have installed PostgreSQL in a non-standard location.
64 # (Please note that in the following comments, it is assumed that <Your Path>
65 # points to the root directory of the include directory of PostgreSQL.)
66 # Then you have three options.
67 # 1) After CMake runs, set PostgreSQL_INCLUDE_DIR to <Your Path>/include and
68 # PostgreSQL_LIBRARY_DIR to wherever the library pq (or libpq in windows) is
69 # 2) Use CMAKE_INCLUDE_PATH to set a path to <Your Path>/PostgreSQL<-version>. This will allow find_path()
70 # to locate PostgreSQL_INCLUDE_DIR by utilizing the PATH_SUFFIXES option. e.g. In your CMakeLists.txt file
71 # set(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "<Your Path>/include")
72 # 3) Set an environment variable called ${PostgreSQL_ROOT} that points to the root of where you have
73 # installed PostgreSQL, e.g. <Your Path>.
