Raw Normal View History

Simplify CMake per-source license notices 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.

FindCups: add imported target
2019-02-05 05:51:20 +00:00
This module defines :prop_tgt:`IMPORTED` target ``Cups::Cups``, if Cups has
been found.
Result variables
^^^^^^^^^^^^^^^^
This module will set the following variables in your project:
``CUPS_FOUND``
true if CUPS headers and libraries were found
``CUPS_INCLUDE_DIRS``
the directory containing the Cups headers
``CUPS_LIBRARIES``
the libraries to link against to use CUPS.
``CUPS_VERSION_STRING``
the version of CUPS found (since CMake 2.8.8)
Cache variables
^^^^^^^^^^^^^^^
The following cache variables may also be set:
``CUPS_INCLUDE_DIR``
the directory containing the Cups headers

Find* (and some other): use ${CMAKE_CURRENT_LIST_DIR} in include() This solves a lots of warnings, e.g. in the FindModulesExecuteAll test. If the installed version on the system is rather old this may even lead to bugs, e.g. https://bugs.gentoo.org/show_bug.cgi?id=436540

Find*: Make find_package(.. QUIET) affect Check* modules. Fixes issues #14812 and #14813 where find_package(OpenMP QUIET) and find_package(Qt4 QUIET) would still print out messages when calling check*() functions. Also a partial fix for #14445 where building CMake (without cmake-gui) when Qt5 is installed and Qt4 is not installed and warnings come out of FindQt4.cmake.
