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.
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.

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.
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.
- 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
- 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.
- Added EXACT option to request an exact version.
- Enforce version using check provided by package.
- Updated FindPackageTest to test versioning in config mode.
- Use CMAKE_PREFIX_PATH and CMAKE_SYSTEM_PREFIX_PATH among other means
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.
