Ben Boeckel 270eb96df0 strings: Remove cmStdString references
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.

Brad King d2059d2511 cmVersion: Fix CMake_VERSION_ENCODE for date in patch level
Use a uint64_t to store encoded version numbers so we have plenty of
bits available.  Encode with room for up to 1000 minor releases between
major releases and to encode dates until the year 10000 in the patch
level.  This is necessary because CMake development versions prior to
release 2.8.0 used the date in the patch level, and this practice may be
restored after the 3.0 release.

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.

Alex Neundorf 1f8f58a0b9 fix #13195: avoid multiple mentions of found packages
Now before adding a package to the list of found or not-found
packages, the package is remvoed from both lists before.

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.

Brad King b0cd630521 Refactor find_* command final path list computation
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.

Brad King b41ad3b399 Teach find_(library|package) about Linux multiarch (#12037)
Implement support for multiarch as specified here:

  http://wiki.debian.org/Multiarch
  https://wiki.ubuntu.com/MultiarchSpec

Detect the <arch> part of <prefix>/lib/<arch> from the implicit library
search path from each compiler to set CMAKE_<lang>_LIBRARY_ARCHITECTURE.
Define CMAKE_LIBRARY_ARCHITECTURE using one of these values (they should
all be the same).  Teach the find_library and find_package commands to
search <prefix>/lib/<arch> whenever they would search <prefix>/lib.

Brad King b95f3cac91 find_package: Check both 32-bit and 64-bit registry views
The system package registry is under HKEY_LOCAL_MACHINE\SOFTWARE which
has separate views for 32-bit and 64-bit applications.  Look in both
views, but prefer the architecture matching the build target platform.

Brad King a0d76c10a7 find_package: Search a "system package registry"
Generalize the "user package registry" created by commit ed0650f6 (Teach
find_package to search a "package registry", 2009-09-01).  Define a
corresponding "system" registry key under HKEY_LOCAL_MACHINE.  This
gives package installers a place to create a registry value that points
at the right location for find_package() to locate the package.

Alex Neundorf 0367245f0c Replace the two vector<string,string> with one vector<struct{string,string}>
Before this patch there were two separate vectors, and the code made sure
they always had the same size.
With this patch the code doesn't have to ensure this anymore, there is only
one vector now.

Todd Gamblin 1221581aa8 Teach find_* commands to ignore some paths
Add platform configuration variable CMAKE_SYSTEM_IGNORE_PATH and user
configuration variable CMAKE_IGNORE_PATH.  These specify a set of
directories that will be ignored by all the find commands.  Update
FindPackageTest so that several cases will fail without a functioning
CMAKE_IGNORE_PATH.

Brad King 71910b3fd4 Fix find_package() when <pkg>_DIR is wrong
When <pkg>_DIR is set to an incorrect version we search again and store
the result in the variable, even if it is <pkg>_DIR-NOTFOUND.

There was a bug in the case when the new search does not find anything
and the old value came from a cache entry with UNINITALIZED type.  The
command used to try to load a package configuration file from the last
place searched, and would leave the old wrong value in the entry.  This
commit fixes the behavior to avoid trying to load a missing file and to
set the value to <pkg>_DIR-NOTFOUND as expected.

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.

leaving them unset.  This simplifies version number handling for find-

since some packages use them.
