* CheckIncludeFiles: Honor CMAKE_REQUIRED_LIBRARIESBrad King2018-04-181-0/+27
| | | | | | | | | | | | | Other check modules honor this variable, so include file checks should too. Add policy `CMP0075` to enable the behavior in a compatible way. This change was originally made by commit v3.11.0-rc1~108^2 (CheckIncludeFiles: Honor CMAKE_REQUIRED_LIBRARIES, 2017-12-24) but it was reverted by commit v3.11.1~9^2 (Revert "CheckIncludeFiles: Honor CMAKE_REQUIRED_LIBRARIES", 2018-04-04) because the behavior change could affect checks in existing projects in an incompatible way. Fixes: #9514
* Revert "CheckIncludeFiles: Honor CMAKE_REQUIRED_LIBRARIES"Brad King2018-04-041-3/+0
| | | | | | | | | | This reverts commit v3.11.0-rc1~108^2 (CheckIncludeFiles: Honor CMAKE_REQUIRED_LIBRARIES, 2017-12-24). The behavior change can affect checks in existing projects that don't expect the behavior. Introducing the behavior again will require a policy. Fixes: #17874 Issue: #9514
* CheckIncludeFiles: Honor CMAKE_REQUIRED_LIBRARIESDon Hinton2018-01-101-0/+3
| | | | | | | | This is needed when cross compiling and the compiler requires a specific linker different from the default, e.g., when cross compiling from Darwin to Linux and passing `-fuse-ld=lld` to clang. Fixes: #9514

* Simplify CMake per-source license noticesBrad King2016-09-271-13/+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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.
* Use string(APPEND) in ModulesDaniel Pfeifer2016-07-271-1/+1
| | | | | | | Automate with: find Modules -type f -print0 | xargs -0 perl -i -0pe \ 's/set\(([a-zA-Z0-9_]+)(\s+)"\$\{\1\}([^"])/string(APPEND \1\2"\3/g'
* Help: Revise CheckIncludeFile* documentationBrad King2015-06-251-19/+18
| | | | | Improve formatting. Link from each module to the other two. Explain the command signatures in more detail.
* Help: Document that the CHECK_* macros create cache variablesSebastian Leske2014-09-111-0/+1
| | | | Otherwise callers may expect to be able to re-use result variables.
* Check*: Add compatibility hack for old VXL codeBrad King2014-08-181-1/+1
| | | | | | | | | | | | | The cleanup in commit 4f2fcce4 (Check*: Allow result variables to contain regex special characters, 2014-07-31) broke old VXL code that abuses the old "if(MATCHES)" implementation by using SET( ${VARIABLE} ${VARIABLE} ) to reset a check result variable. Add a compatibility hack to the CheckFunctionExists, CheckIncludeFileCXX, and CheckSymbolExists modules to re-run their checks when the result variable is set to its own name. Use STREQUAL instead of MATCHES so that special characters still work.
* Check*: Allow result variables to contain regex special characters (#14923)Brad King2014-07-311-1/+1
| | | | | | | | | | | | | | | | | | Prior to the existence of the if(DEFINED) condition, many of our Check modules implemented the condition with a hack that takes advantage of the auto-dereference behavior of the if() command to detect if a variable is defined. The hack has the form: if("${VAR} MATCHES "^${VAR}$") where "${VAR}" is a macro argument reference. However, this does not work when the variable named in the macro argument contains characters that have special meaning in regular expressions, such as '+'. Run the command git grep -E 'if\("\$\{.*\}" MATCHES "\^\$\{.*\}\$"\)' -- Modules/Check* to identify lines with this problem. Use if(NOT DEFINED) instead.
* Check*.cmake : Add CMAKE_REQUIRED_QUIET flag.Clinton Stimpson2014-03-301-3/+10
| | | | | Setting this flag can silence messages from the Check*.cmake modules. This can be used by Find*.cmake modules when they are in silent mode.
* Drop use of configure_file IMMEDIATE optionDaniele E. Domenichelli2013-11-131-1/+1
| | | | | | Since commit 7d47c693 (Drop compatibility with CMake < 2.4, 2013-10-08) we no longer need to use the configure_file IMMEDIATE option to support compatibility modes less than 2.0.
* Convert builtin help to reStructuredText source filesKitware Robot2013-10-151-11/+25
| | | | | | | | Run the convert-help.bash script to convert documentation: ./convert-help.bash "/path/to/CMake-build/bin" Then remove it.
* 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"'\(\s*\)(.\+)/'"$c"'\1()/' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | egrep -z -v 'Tests/CMakeTests/While-Endwhile-' | xargs -0 sed -i -f convert.sed && rm convert.sed
* Convert CMake-language commands to lower caseKitware Robot2012-08-131-30/+30
| | | | | | | | | | | | | | | | | Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case. Run the following shell code: cmake --help-command-list | grep -v "cmake version" | while read c; do echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | xargs -0 sed -i -f convert.sed && rm convert.sed
* Remove trailing whitespace from most CMake and C/C++ codeKitware Robot2012-08-131-6/+6
| | | | | | | | | | | | | | | | | Our Git commit hooks disallow modification or addition of lines with trailing whitespace. Wipe out all remnants of trailing whitespace everywhere except third-party code. Run the following shell code: git ls-files -z -- \ bootstrap doxygen.config '*.readme' \ '*.c' '*.cmake' '*.cpp' '*.cxx' \ '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \ '*.mm' '*.pike' '*.py' '*.txt' '*.vim' | egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' | egrep -z -v '^(Modules/CPack\..*\.in)' | xargs -0 sed -i 's/ \+$//'

| | | | | | | This adds copyright/license notification blocks CMake's non-find modules. Most of the modules had no notices at all. Some had notices referring to the BSD license already. This commit normalizes existing notices and adds missing notices.
