* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.
* Fix spelling typos in comments and documentation (#16037)Felix Geyer2016-03-291-1/+1
| | | | | The Debian package checker tool (lintian) detected several typos in CMake.
* FindThreads: make the call to try_run() work also if only C++ is enabledRolf Eike Beer2015-09-251-1/+8
| | | | This isn't enough to make the whole module work with only C++ enabled.
* FindThreads: replace CheckIncludeFiles by CheckIncludeFileRolf Eike Beer2015-09-251-3/+15
| | | | | | While at it, also add a branch using CheckIncludeFileCXX. Also give a better error message if no supported language is enabled. C++ support isn't working yet, but it has never worked.
* FindThreads: introduce THREADS_PREFER_PTHREAD_FLAG (#14767)Rolf Eike Beer2014-10-081-0/+18
|
* FindThreads: introduce an imported target to link toTimo Rothenpieler2014-10-081-0/+18
| | | | | | This not only holds the library, but can also hold compiler flags needed, e.g. the -pthread flag preferred by gcc on some platforms. There was no clean way to get that compiler flag from the module until now.
* FindThreads: move checking of the -pthread compiler flag into a macroRolf Eike Beer2014-10-061-36/+42
| | | | | | This allows a following commit to introduce a switch to prefer that check over searching for the explicit library names without breaking backward compatibility.

* Remove .* expressions from beginning and end of MATCHES regexsRolf Eike Beer2014-04-141-2/+2
| | | | | | | | | All these expressions work the same: "foo" ".*foo.*" "^.*foo.*$" This assumes that the "Intel*" expressions were meant to be "Intel.*".
* Find*: Make find_package(.. QUIET) affect Check* modules.Clinton Stimpson2014-03-301-0/+3
| | | | | | | | | | 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.

* Remove CMake-language block-end command argumentsKitware Robot2012-08-131-8/+8
| | | | | | | | | | | | | | | | | Ancient versions of CMake required else(), endif(), and similar block termination commands to have arguments matching the command starting the block. This is no longer the preferred style. Run the following shell code: for c in else endif endforeach endfunction endmacro endwhile; do echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | egrep -z -v 'Tests/CMakeTests/While-Endwhile-' | xargs -0 sed -i -f convert.sed && rm convert.sed
* Convert CMake-language commands to lower caseKitware Robot2012-08-131-94/+94
| | | | | | | | | | | | | | | | | Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case. Run the following shell code: cmake --help-command-list | grep -v "cmake version" | while read c; do echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | xargs -0 sed -i -f convert.sed && rm convert.sed

| | | | | | | | | | | | | | | | | Our Git commit hooks disallow modification or addition of lines with trailing whitespace. Wipe out all remnants of trailing whitespace everywhere except third-party code. Run the following shell code: git ls-files -z -- \ bootstrap doxygen.config '*.readme' \ '*.c' '*.cmake' '*.cpp' '*.cxx' \ '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \ '*.mm' '*.pike' '*.py' '*.txt' '*.vim' | egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' | egrep -z -v '^(Modules/CPack\..*\.in)' | xargs -0 sed -i 's/ \+$//'
* FindThreads: Try pthreads with no special option first (#11333)Rolf Eike Beer2012-01-211-19/+28
| | | | | | | QNX has the phtread stuff in the standard library. The best way would IMHO be to check if a program that uses pthread_* can be successfully linked without specifying any linker option before trying out the different flags.

* Modules: Include builtin FindPackageHandleStandardArgs directlyBrad King2011-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FindPackageHandleStandardArgs module was originally created outside of CMake. It was added for CMake 2.6.0 by commit e118a627 (add a macro FIND_PACKAGE_HANDLE_STANDARD_ARGS..., 2007-07-18). However, it also proliferated into a number of other projects that at the time required only CMake 2.4 and thus could not depend on CMake to provide the module. CMake's own find modules started using the module in commit b5f656e0 (use the new FIND_PACKAGE_HANDLE_STANDARD_ARGS in some of the FindXXX modules..., 2007-07-18). Then commit d358cf5c (add 2nd, more powerful mode to find_package_handle_standard_args, 2010-07-29) added a new feature to the interface of the module that was fully optional and backward compatible with all existing users of the module. Later commit 5f183caa (FindZLIB: use the FPHSA version mode, 2010-08-04) and others shortly thereafter started using the new interface in CMake's own find modules. This change was also backward compatible because it was only an implementation detail within each module. Unforutnately these changes introduced a problem for projects that still have an old copy of FindPackageHandleStandardArgs in CMAKE_MODULE_PATH. When any such project uses one of CMake's builtin find modules the line include(FindPackageHandleStandardArgs) loads the copy from the project which does not have the new interface! Then the including find module tries to use the new interface with the old module and fails. Whether this breakage can be considered a backward incompatible change in CMake is debatable. The situation is analagous to copying a standard library header from one version of a compiler into a project and then observing problems when the next version of the compiler reports errors in its other headers that depend on its new version of the original header. Nevertheless it is a change to CMake that causes problems for projects that worked with previous versions. This problem was discovered during the 2.8.3 release candidate cycle. It is an instance of a more general problem with projects that provide their own versions of CMake modules when other CMake modules depend on them. At the time we resolved this instance of the problem with commit b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake everywhere, 2010-09-28) for the 2.8.3 release. In order to address the more general problem we introduced policy CMP0017 in commit db44848f (Prefer files from CMAKE_ROOT when including from CMAKE_ROOT, 2010-11-17). That change was followed by commit ce28737c (Remove usage of CMAKE_CURRENT_LIST_DIR now that we have CMP0017, 2010-12-20) which reverted the original workaround in favor of using the policy. However, existing project releases do not set the policy behavior to NEW and therefore still exhibit the problem. We introduced in commit a364daf1 (Allow users to specify defaults for unset policies, 2011-01-03) an option for users to build existing projects by adding -DCMAKE_POLICY_DEFAULT_CMP0017=NEW to the command line. Unfortunately this solution still does not allow such projects to build out of the box, and there is no good way to suggest the use of the new option. The only remaining solution to keep existing projects that exhibit this problem building is to restore the change originally made in commit b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake everywhere, 2010-09-28). This also avoids policy CMP0017 warnings for this particular instance of the problem the policy addresses.
* Remove usage of CMAKE_CURRENT_LIST_DIR now that we have CMP0017Alex Neundorf2011-01-041-1/+1
| | | | | | | | This puts the new search behaviour for included files in action, i.e. now when a file from Modules/ include()s another file, it also gets the one from Modules/ included, i.e. the one it expects. Alex
* Use absolute path to FindPackageHandleStandardArgs.cmake everywhereAlex Neundorf2010-09-281-1/+1
| | | | | | | This is to avoid getting an (older) copy of FPHSA.cmake which is e.g. installed with KDE 4.5.0 and 4.5.1. Alex

| | | | | | | | | | | | FindThreads.h BUG: improve CheckC(XX)SourceRuns.cmake so that it works with cross compiling, the return value has to go in the cache but shouldn't overwrite the actual return value, and it should go only in the cache if we have a result from try_run() otherwise we won't get here again if we have a result later on Alex
* ENH: improve TRY_RUN() for crosscompiling: instead of just failing, it nowAlexander Neundorf2007-06-011-1/+1
| | | | | | | | | | | | | | | creates two cache variables, one for the RUN_RESULT, one for the RUN_OUTPUT (if required), which can be set or preset by the user. It has now also two new arguments: RUN_OUTPUT_VARIABLE and COMPILE_OUTPUT_VARIABLE (the old OUTPUT_VARIABLE merges both), so if only COMPILE_OUTPUT_VARIABLE is used the run time output of the TRY_RUN is unused and the user doesn't have to care about the output when crosscompiling. This is now used in FindThreads.cmake, CheckC/CXXSourceRuns.cmake and TestBigEndian.cmake, which used the output only for the logfile (compile output is still there). Test/TryCompile/ now also tests the behaviour of OUTPUT_VARIABLE, RUN_OUTPUT_VARIABLE and COMPILE_OUTPUT_VARIABLE. Alex
