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names and years are hard to maintain and often out-of-date or plain wrong.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.
Teach the module to handle SYSCONFDIR and LOCALSTATEDIR properly if
CMAKE_INSTALL_PREFIX is set to `/` or `/usr` -- i.e. as expected by GNU
Coding Standard (i.e. set SYSCONFDIR to `/etc` and `LOCALSTATEDIR` to
`/var`). Also if CMAKE_INSTALL_PREFIX is set to /opt/pkg, `SYSCONFDIR`
must be set to `/etc/opt/pkg` and `LOCALSTATEDIR` to `/var/opt/pkg`
according to FHS.
Convert several preformatted code block literals that enumerate lists of
options or variables to use reST definition lists instead. Manually
wrap other long lines in code blocks.
When not installing in /usr (i.e. /usr/local) on Debian/Ubuntu, the
multiarch path is not in ldconfig path, and therefore libraries cannot
be found, unless the user manually modifies the files in
/etc/ld.so.conf.d, in order to include /usr/local/lib/<arch>.
This patch fixes this issue by using "lib/<arch>" only if the user is
installing the software in /usr, and uses "lib" in all the other cases.
The AMD64 ABI document http://www.x86-64.org/documentation/abi.pdf
does specify that 64bits binary libraries should end up in <prefix>/lib64
and 32bits ones in <prefix>/lib. All but debian based distros do so,
and some like OpenSUSE even enforce the rule when packaging with RPM
and refuse to build the RPM if this is not the case.
After some discussion (see the bug notes) we cannot do that behind
the scene and the current fix supposes that the user shall use
the CMAKE_INSTALL_LIBDIR variables content in its INSTALL rules if
he wants to put the lib in the right place. CMAKE_INSTALL_LIBDIR
shall have the appropriate value depending on the Linux distribution
found and 32/64bitness of the host.
The cross-compiling case (even 32bits compile on a 64bits host)
is not handled.
