Brad King 7d47c69365 Drop compatibility with CMake < 2.4
Drop all behavior activated by setting CMAKE_BACKWARDS_COMPATIBILITY to
a value lower than 2.4, and generate an error when projects or the user
attempt to do so.  In the error suggest using a CMake 2.8.x release.

Teach cmake_minimum_required to warn about projects that do not require
at least CMake 2.4.  They are not supported by CMake >= 3.0.

Replace the documentation of CMAKE_BACKWARDS_COMPATIBILITY with a
reference to policy CMP0001.

Brad King 179f495602 find_package: Reword <package>_NO_INTERFACES documentation 2013-02-01 10:30:57 -05:00
Stephen Kelly 2c3654c3de Add a way to exclude INTERFACE properties from exported targets.
Projects set interface requirements upstream, and existing
downstreams use of target_link_libraries will consume those interfaces.

This can create a backward compatibility concern as the result may
be changing the order of include directories of downstreams, or another
side-effect of using the INTERFACE properties.

Provide a way for them to emulate the behavior of a version-based
policy in the config file.

Alex Neundorf 6f50a04cc1 exports: define a CMAKE_FIND_PACKAGE_NAME var set by find_package()
This way the name of the searched package can be accessed in find-modules,
config-files and more importantly in generated target export files.
This is now used when a target export file detects that a required
target does not exist.

Brad King 6c12e820b8 find_package: Document <package>_FIND_* variables (#13142)
When loading a find module or package config file the find_package
command defines several variables to provide information about the
caller's request.  Previously this was documented only in the
Modules/readme.txt file which is not distributed.  Document the
behavior explicitly in the main find_package documentation.

Alex Neundorf 16c0c7376c find_package: allow <pkg>Config.cmake to set <pkg>_FOUND to FALSE
Before, find_package in Config mode always set Foo_FOUND to true if the
Config file has been found and could be executed.
If the Config file itself detected some problem, like a missing dependency,
it did not have a way to signal to the outside that the package is not working.
With this patch, if a Config file sets Foo_FOUND to FALSE, this is taken into
account and not overridden.

Brad King d3651041e9 find_package: Optionally warn when implicitly using Config mode
Define variable CMAKE_FIND_PACKAGE_WARN_NO_MODULE for use by a project
that wants to use an explicit mode in every call to find_package in
order to generate more specific failure messages.  Word the warning
using the new CONFIG and MODULE mode keywords when the minimum required
version of CMake is new enough to have them.  Otherwise word the warning
using the old NO_MODULE mode keyword.

Alex Neundorf 7d67dcf52b find_package: improve error message when no Find module is present
Explain exactly why CMake is looking for a package configuration file
and who is expected to provide what:

 CMake Error at CMakeLists.txt:7 (find_package):
  By not providing "Find<pkg>.cmake" in CMAKE_MODULE_PATH the caller
  has asked CMake to find a package configuration file provided by
  "<pkg>", but CMake did not find one.

  Could not find a package configuration file provided by "<pkg>"
  with any of the names:

    <pkg>Config.cmake
    <pkg>-config.cmake

  Add the installation prefix of "<pkg>" to CMAKE_PREFIX_PATH or
  set "<pkg>_DIR" to a directory containing one of the above files.
  If "<pkg>" provides separate development package or SDK be sure
  it has been installed.

The first paragraph explains how CMake is interpreting the intention of
the caller.  This puts the blame or credit at the call site in the
project code where it belongs both when it is a bug and when it is
intentional.  It can be dropped in NO_MODULE mode.

This macro can be used to generate basic version files which can be

the COMPATIBILITY mode to a filename and configure_file()s the
resulting file.

all be the same).  Teach the find_library and find_package commands to
