[CMake] CPack install directory

[David Cole]

This reply applies to CVS CMake only. This functionality is new and is *not*
in the CMake-2-4 branch.

In your main CMakeLists.txt file (or wherever you set all your other CPack
options) do something like this:
  CONFIGURE_FILE("${MyProject_SOURCE_DIR}/MyProjectCPackOptions.cmake.in"
    "${MyProject_BINARY_DIR}/MyProjectCPackOptions.cmake" @ONLY)
  SET(CPACK_PROJECT_CONFIG_FILE
"${MyProject_BINARY_DIR}/MyProjectCPackOptions.cmake")

And then in the file
"${MyProject_SOURCE_DIR}/MyProjectCPackOptions.cmake.in" do this:
  IF("${CPACK_GENERATOR}" STREQUAL "DEB")
    SET(CPACK_PACKAGING_INSTALL_PREFIX "/")
  ENDIF("${CPACK_GENERATOR}" STREQUAL "DEB")

The CPACK_PROJECT_CONFIG_FILE, if there is one, is read during package
generation by CPack. It is read once for each generator and CPACK_GENERATOR
will be set to the exact generator being used. The
CPACK_PACKAGING_INSTALL_PREFIX is used as the root of the install tree when
building the end user installer package.


Hope this helps, (sorry it took a while to reply)
