Brad King ed0650f6ae Teach find_package to search a "package registry"
A common user workflow is to build a series of dependent projects in
order.  Each project locates its dependencies with find_package.  We
introduce a "user package registry" to help find_package locate packages
built in non-standard search locations.

The registry explicitly stores locations of build trees providing
instances of a given package.  There is no defined order among the
locations specified.  These locations should provide package
configuration files (<package>-config.cmake) and package version files
(<package>-config-version.cmake) so that find_package will recognize the
packages and test version numbers.

Brad King c332e0bf3c ENH: Isolate policy changes in included scripts
Isolation of policy changes inside scripts is important for protecting
the including context.  This teaches include() and find_package() to
imply a cmake_policy(PUSH) and cmake_policy(POP) around the scripts they
load, with a NO_POLICY_SCOPE option to disable the behavior.  This also
creates CMake Policy CMP0011 to provide compatibility.  See issue #8192.

Alexander Neundorf ef3e48c3d5 ENH: when trying to find a FooConfig.cmake file, if in the directory pointed
to by the Foo_DIR variable there is no FooConfig.cmake file, then instead of
abort and complain that the user should set or clear the Foo_DIR variables,
just search for the file and discard the old Foo_DIR contents

The tests succeed, ok by Brad.

Brad King ae28ec9f24 ENH: Preserve <pkg>_FIND_XXX vars in find_package
When the find_package command loads a module it sets several
<pkg>_FIND_XXX variables to communicate information about the command
invocation to the module.  This restores the original state of the
variables when the command returns.  This behavior is useful when a
find-module recursively calls find_package with NO_MODULE so that the
inner call does not change the values in the find-module.

Brad King 994262e5cc ENH: Improve find_package version numbering
Make the number of version components specified explicitly available.
Set variables for unspecified version components to "0" instead of
leaving them unset.  This simplifies version number handling for find-
and config-modules.  Also support a fourth "tweak" version component
since some packages use them.

Alexander Neundorf 8903f88b36 ENH: provide the xxx_FIND_QUIETLY, xxx_FIND_REQUIRED and xxx_FIND_VERSION_ variables
also in Config mode, so the xxxConfig.cmake files can e.g. test the QUIETLY
parameter and print something or not

Brad King 2b96e0edab ENH: Teach find_package about lib64 paths
When find_package is about to look in <prefix>/lib, search first in
<prefix>/lib64 in cases that find_library would use lib64 paths.

Brad King 5b406c9044 ENH: Add HINTS option to find_* commands.
- Hints are searched after user locations but before system locations
  - The HINTS option should have paths provided by system introspection
  - The PATHS option should have paths that are hard-coded guesses

Brad King 789c167b6f ENH: Refactor cmFindCommon, cmFindBase, and cmFindPackageCommand
- Add each part of the search order in a separate method.
  - Collect added paths in an ivar in cmFindCommon.
  - Move user path storage up to cmFindCommon and share
    between cmFindBase and cmFindPackageCommand.
  - Expand user path registry values up in cmFindCommon
    - Enables 32-/64-bit registry view for find_package
    - Disables registry expansion for paths not specified
      with the PATHS argument, which is not expected.

Brad King f41b1e8e91 ENH: Implement version support in the find_package command module mode. Version numbers provided to the command are converted to variable settings to tell the FindXXX.cmake module what version is requested. This addresses issue #1645. 2008-01-21 08:48:33 -05:00
Brad King b424df917d ENH: Major improvements to the FIND_PACKAGE command. See bug #3659.

    to locate package configuration files.
  - Create cmFindCommon as base for cmFindBase and cmFindPackageCommand
  - Move common functionality up to cmFindCommon
  - Improve documentation of FIND_* commands.
  - Fix FIND_* commands to not add framework/app paths in wrong place.
