  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)

  21. # ----------------------------------------------------------------------------
  22. # History:
  23. # This module is derived from the module originally found in the VTK source tree.
  24. #
  25. # ----------------------------------------------------------------------------
  26. # Note:
  27. # PostgreSQL_ADDITIONAL_VERSIONS is a variable that can be used to set the
  28. # version mumber of the implementation of PostgreSQL.
  29. # In Windows the default installation of PostgreSQL uses that as part of the path.
  30. # E.g C:\Program Files\PostgreSQL\8.4.
  31. # Currently, the following version numbers are known to this module:
  32. # "9.1" "9.0" "8.4" "8.3" "8.2" "8.1" "8.0"
  33. #
  34. # To use this variable just do something like this:
  35. # set(PostgreSQL_ADDITIONAL_VERSIONS "9.2" "8.4.4")
  36. # before calling find_package(PostgreSQL) in your CMakeLists.txt file.
  37. # This will mean that the versions you set here will be found first in the order
  38. # specified before the default ones are searched.
  39. #
  40. # ----------------------------------------------------------------------------
  41. # You may need to manually set:
  42. # PostgreSQL_INCLUDE_DIR - the path to where the PostgreSQL include files are.
  43. # PostgreSQL_LIBRARY_DIR - The path to where the PostgreSQL library files are.
  44. # If FindPostgreSQL.cmake cannot find the include files or the library files.
  45. #
  46. # ----------------------------------------------------------------------------
  47. # The following variables are set if PostgreSQL is found:
  48. # PostgreSQL_FOUND - Set to true when PostgreSQL is found.
  49. # PostgreSQL_INCLUDE_DIRS - Include directories for PostgreSQL
  50. # PostgreSQL_LIBRARY_DIRS - Link directories for PostgreSQL libraries
  51. # PostgreSQL_LIBRARIES - The PostgreSQL libraries.
  52. #
  53. # ----------------------------------------------------------------------------
  54. # If you have installed PostgreSQL in a non-standard location.
  55. # (Please note that in the following comments, it is assumed that <Your Path>
  56. # points to the root directory of the include directory of PostgreSQL.)
  57. # Then you have three options.
  58. # 1) After CMake runs, set PostgreSQL_INCLUDE_DIR to <Your Path>/include and
  59. # PostgreSQL_LIBRARY_DIR to wherever the library pq (or libpq in windows) is
  60. # 2) Use CMAKE_INCLUDE_PATH to set a path to <Your Path>/PostgreSQL<-version>. This will allow find_path()
  61. # to locate PostgreSQL_INCLUDE_DIR by utilizing the PATH_SUFFIXES option. e.g. In your CMakeLists.txt file
  62. # set(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "<Your Path>/include")
  63. # 3) Set an environment variable called ${PostgreSQL_ROOT} that points to the root of where you have
  64. # installed PostgreSQL, e.g. <Your Path>.
  65. #
