Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
The fix in commit commit v3.6.0-rc1~82^2 (Drop find_(library|file|path)
prefixes from PATH on non-Windows, 2016-05-09) aggressively dropped
search of the entries in PATH itself in addition to the prefixes derived
from it. This regresses find modules that (incorrectly) depended on the
behavior, including some of our own modules such as FindImageMagick.
Restore the search of entries in PATH itself. If we want to drop it
later we will need to do so with a policy. Fixes#16192.
Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.

Since commit v3.3.0-rc1~430^2 (Teach find_(library|file|path) to get
prefixes from PATH, 2015-02-18) we search in <prefix>/include and
<prefix>/lib directories for prefixes with bin directories in the PATH
environment variable. The motivation was to support MSYS, MinGW and
similar Windows platforms in their default environments automatically.
At the time this behavior was thought to be worthwhile in general.

Refactoring in the topic merged by commit v3.2.0-rc1~400 (Merge topic
'refactor-search-path-construction', 2014-11-13) introduced a bug that
filters out duplicate paths in an incorrect order. Restore the search
path to its documented order even when duplicate paths are present.

This topic was never tested without some follow-up commits. The
GetCacheEntryValue API returns a pointer to memory freed on return.
It will have to be revised along with the rest of the original topic.

The find_package command already knows how to compute installation
prefixes from PATH. Use the same approach to establish prefixes for
find_library, find_file, and find_path to use to look in directories
like "<prefix>/lib[/<arch>]" and "<prefix>/include" for libraries and
headers. This will reduce the amount of configuration end users need to
do to establish a work environment rooted under a specific prefix.
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.
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.
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.
Implement support for multiarch include directories as specified here:
https://wiki.ubuntu.com/MultiarchCross
Generalize the multiarch feature added in commit b41ad3b3 (Teach
find_(library|package) about Linux multiarch, 2011-06-08) to the
find_path and find_file commands. Teach them to search
<prefix>/include/<arch> whenever they would search <prefix>/include.
When more than one value is given to the NAMES option this command by
default will consider one name at a time and search every directory for
it. Add a NAMES_PER_DIR option to tell this command to consider one
directory at a time and search for all names in 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.
Implement support for multiarch as specified here:
http://wiki.debian.org/Multiarchhttps://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.
Previously the command
find_path(VAR DOC "")
would crash because the argument pre-processing removed the DOC ""
arguments but the rest of the parsing assumes at least 2 arguments.
Reject the call with an error instead.
Delay computation of the command documentation until it is needed.
It is wasteful to do it in the constructor on every call.

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.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
This clarifies documentation of the find_* commands' PATH_SUFFIXES
option. The option adds paths with the suffixes but does not remove the
paths without the suffixes.
In cmFindBase we were searching all path suffixes appended to all paths
before considering the paths without any suffixes. Instead we should
consider each path with and without suffixes before moving to the next
path. See issue #7783.
- The short-hand forms do not document the NO_* options.
- CMake 2.4 and 2.6.0 accepted them accidentally, but also
treated the options as paths.
- Now the options are accepted but do not become paths.
- The CMAKE_PREFIX_PATH and similar variables have both
environment and CMake cache versions.
- Previously the environment value was checked before the
cache value.
- Now the cache value is favored because it is more specific.
- 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
- CMAKE_FIND_FRAMEWORK and CMAKE_FIND_APPBUNDLE are supposed to specify
whether to find frameworks/appbundles FIRST, LAST, ONLY, or NEVER.
- Previously this affected only the placement of CMAKE_FRAMEWORK_PATH
and CMAKE_APPBUNDLE_PATH with respect to the other path specifiers.
- Now it behaves as documented. The entire search path is inspected for
each kind of program, library, or header before trying the next kind.
- Additionally the ONLY mode is now honored for headers so that users
do not end up with a library in framework and a header from elsewhere.
- In cmFindBase when CheckCommonArgument returns true, set newStyle
- Otherwise if there are no PATHS then the ancient-style compatibility
mode is enabled and the common argument is treated as a path.
- 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.
- cmFindBase should search both 32-bit and 64-bit registry views
for FIND_PROGRAM even if CMAKE_SIZEOF_VOID_P is not set.
- Needed because the variable is not available when CMAKE_MAKE_PROGRAM
is to be found.
