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

|
4 #
|
|
|
5 # This module defines
|
|
|
6 # PostgreSQL_LIBRARIES - the PostgreSQL libraries needed for linking
|
|
|
7 # PostgreSQL_INCLUDE_DIRS - the directories of the PostgreSQL headers
|
|
|
8 # PostgreSQL_VERSION_STRING - the version of PostgreSQL found (since CMake 2.8.8)

|
24 # History:
|
|
|
25 # This module is derived from the module originally found in the VTK source tree.
|
|
|
26 #
|
|
|
27 # ----------------------------------------------------------------------------
|
|
|
28 # Note:
|
|
|
29 # PostgreSQL_ADDITIONAL_VERSIONS is a variable that can be used to set the
|
|
|
30 # version mumber of the implementation of PostgreSQL.
|
|
|
31 # In Windows the default installation of PostgreSQL uses that as part of the path.
|
|
|
32 # E.g C:\Program Files\PostgreSQL\8.4.
|
|
|
33 # Currently, the following version numbers are known to this module:
|
|
|
34 # "9.1" "9.0" "8.4" "8.3" "8.2" "8.1" "8.0"
|
|
|
35 #
|
|
|
36 # To use this variable just do something like this:
|
|
|
37 # set(PostgreSQL_ADDITIONAL_VERSIONS "9.2" "8.4.4")
|
|
|
38 # before calling find_package(PostgreSQL) in your CMakeLists.txt file.
|
|
|
39 # This will mean that the versions you set here will be found first in the order
|
|
|
40 # specified before the default ones are searched.
|
|
|
41 #
|
|
|
42 # ----------------------------------------------------------------------------
|
|
|
43 # You may need to manually set:
|
|
|
44 # PostgreSQL_INCLUDE_DIR - the path to where the PostgreSQL include files are.
|
|
|
45 # PostgreSQL_LIBRARY_DIR - The path to where the PostgreSQL library files are.
|
|
|
46 # If FindPostgreSQL.cmake cannot find the include files or the library files.
|
|
|
47 #
|
|
|
48 # ----------------------------------------------------------------------------
|
|
|
49 # The following variables are set if PostgreSQL is found:
|
|
|
50 # PostgreSQL_FOUND - Set to true when PostgreSQL is found.
|
|
|
51 # PostgreSQL_INCLUDE_DIRS - Include directories for PostgreSQL
|
|
|
52 # PostgreSQL_LIBRARY_DIRS - Link directories for PostgreSQL libraries
|
|
|
53 # PostgreSQL_LIBRARIES - The PostgreSQL libraries.
|
|
|
54 #
|
|
|
55 # ----------------------------------------------------------------------------
|
|
|
56 # If you have installed PostgreSQL in a non-standard location.
|
|
|
57 # (Please note that in the following comments, it is assumed that <Your Path>
|
|
|
58 # points to the root directory of the include directory of PostgreSQL.)
|
|
|
59 # Then you have three options.
|
|
|
60 # 1) After CMake runs, set PostgreSQL_INCLUDE_DIR to <Your Path>/include and
|
|
|
61 # PostgreSQL_LIBRARY_DIR to wherever the library pq (or libpq in windows) is
|
|
|
62 # 2) Use CMAKE_INCLUDE_PATH to set a path to <Your Path>/PostgreSQL<-version>. This will allow find_path()
|
|
|
63 # to locate PostgreSQL_INCLUDE_DIR by utilizing the PATH_SUFFIXES option. e.g. In your CMakeLists.txt file
|
|
|
64 # set(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "<Your Path>/include")
|
|
|
65 # 3) Set an environment variable called ${PostgreSQL_ROOT} that points to the root of where you have
|
|
|
66 # installed PostgreSQL, e.g. <Your Path>.
