* Simplify CMake per-source license noticesBrad King2016-09-271-14/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.
* Modules: Format documentation to avoid over-long preformatted linesBrad King2014-10-221-9/+15
| | | | | | 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.
* fix inclusion of FPHSARolf Eike Beer2014-10-021-1/+1
| | | | Make sure these modules also include exactly the version shipped with CMake.
* Find*: Make find_package(.. QUIET) affect Check* modules.Clinton Stimpson2014-03-301-0/+1
| | | | | | | | | | 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.
* FindBacktrace: Search and report only when not already foundVadim Zhukov2013-12-191-7/+10
| | | | | | Avoid saying "... detected in default set..." each time CMake is run. Prompted by Rolf Eike Beer on cmake-developers@.
* Add FindBacktrace.cmake module.Vadim Zhukov2013-10-161-0/+91
It designed to search for implementation of backtrace(3) routine. Currently it is used in OpenBSD Ports for building Clementine music player. A lot of input from brad.king@ and neundorf@.
