A few pieces of code have some ambiguous type deduction that seems to
resolve correctly for most compilers but not for the Oracle compiler.
This makes those few instances more explicit.
Manage classes of search paths in labeled containers. This removes the
need to have a seperate member variable for each type of search path, but
also allows path types to be grouped togethor in various different ways
and manipulated as subsets of the full set of search paths.
The functions for adding the various different types of paths have been
factored out into a new class, cmSearchPath. It is to be used as a helper
container class for the various find_* commands.
Prior to this commit, the set of search paths to traverse for find commands
was incrementally constructed. This change allows each group of paths, i.e.
CMakeVariablePaths, UserHintsPaths, SystemEnvironmentPaths, etc. to be
constructed and manipulated independently, and then all combined togethor.
When a project is packaged for redistribution the local package
registries should not be updated or consulted. They are for developers.
Add variables to disable use of package registries globally:
* CMAKE_EXPORT_NO_PACKAGE_REGISTRY that disables the export(PACKAGE)
command
* CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY that disables the User Package
Registry in all the find_package calls.
* CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY that disables the
System Package Registry in all the find_package calls.
Update documentation and unit tests.
Use the clang RemoveCStrCalls tool to automatically migrate the
code. This was only run on linux, so does not have any positive or
negative effect on other platforms.
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.
The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.
Set a global property in the find_package implementation. Track and
reset that property in the find_dependency macro. Read the property
in FeatureSummary when determining whether to print output.
This means that packages which are found only as dependencies are not
listed by FeatureSummary, but if a project uses find_package elsewhere
directly, then it will be listed by FeatureSummary.

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.
This reverts commit 2c3654c3de.
The removal of some tests added in commit 77cecb77 (Add includes and compile
definitions with target_link_libraries., 2012-11-05) are also squashed
into this commit.
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.
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.
Alex
If a config-file sets <package>_FOUND to FALSE, it can now give a reason
using the variable <package>_NOT_FOUND_MESSAGE, which is used by cmFindPackage
and FPHSA.
Alex
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.
This patch adds documentation for OPTIONAL_COMPONENTS to cmFindPackage.cxx,
and also extends Modules/readme.txt significantly with regard to how
components should be handled.
Alex
Add an OPTIONAL_COMPONENTS keyword to find_package() so we can have a
clear distinction between required and optional components. Don't allow
a component to be both required and optional.
Alex
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.
Alex
If in Config mode a configuration file could not be found, cmake printed
an error, but did not actually stop processing. With SetFatalErrorOccured
it does.
Alex
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.

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.

In commit 41c2895b (Added version support to Config mode of find_package
command, 2008-01-28) the error message was computed but was not
reported. Add the SetError call to report it.
All find_* commands re-root the list of paths and then add trailing
slashes. Factor this pair of calls out into a dedicated method. The
new method would be the only caller to AddTrailingSlashes, so subsume
that method into it.
