* FindOpenMP: Avoid warning in check codeBrad King2018-06-271-1/+1
| | | | | | | | | | The test code added by commit v3.12.0-rc1~411^2~1 (FindOpenMP: Verify in test source that OMP library is linked, 2018-03-01) leaves an unused variable warning. This breaks the check with `-Werror`. Remove the variable and leave just the function call, which should still check that the OMP library is linked. Fixes: #18102

| * FindOpenMP: Fix support for Intel on WindowsRoland Schulz2018-04-161-13/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change in commit v3.11.0-rc1~334^2 (FindOpenMP: Use NO_DEFAULT_PATH where appropriate, 2017-11-15) broke partial support for Intel on Windows. Since `OpenMP_${LANG}_IMPLICIT_LINK_DIRS` is empty for this compiler the `find_library` call without `NO_DEFAULT_PATH` worked accidentally in environments with the needed libraries in the search path already. Fix support for Intel on Windows by simply removing our explicit search for the `libiomp5md` library. In cases that it is needed, the compiler already inserts metadata in `.obj` files to tell the MSVC linker to use the library. Suggested-by: Christian Pfeiffer <cpfeiffer@live.de> Fixes: #17910
* | FindOpenMP: Add support for AppleClang compilerHenry Fredrick Schreiner2018-03-071-0/+23

| | | | | | | | Fixes: #17476
* | FindOpenMP: Use NO_DEFAULT_PATH where appropriateChristian Pfeiffer2017-11-151-0/+3
|/ | | | | | | | OpenMP libraries must always be found in the implicit linking directories of a compiler when using the OpenMP compile flag. If a suitable OpenMP library is also found in for example some CMAKE_PREFIX_PATH, this can lead to the module finding the incorrect library. On the other hand, CMAKE_PREFIX_PATH can't ever be a location that we need to consider since the OpenMP compile flag would not work if we needed to.

* FindOpenMP: Avoid CMP0054 warningsBrad King2017-09-221-0/+1
| | | | | | | | | | | | | | When invoked in projects that don't set CMP0054 to NEW, FindOpenMP triggers a warning: CMake Warning (dev) at .../Modules/FindOpenMP.cmake:... (if): Policy CMP0054 is not set...Quoted variables like "c" will no longer be dereferenced when the policy is set to NEW. Since the policy is not set the OLD behavior will be used.

| | | | | | | Try `-fopenmp=libiomp5` in addition to `-fopenmp=libomp`. Leave the latter as the default that we try first when the compiler id is `Clang`. If that does not work we will still fall back to trying all the candidates and eventually get to the iomp5 variant.
* Simplify CMake per-source license noticesBrad King2016-09-271-16/+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.

* Find*: Make find_package(.. QUIET) affect Check* modules.Clinton Stimpson2014-03-301-2/+10

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 Robot2012-08-131-5/+5
| | | | | | | | | | | | | | | | | 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

* FindOpenMP: try the most likely flags firstRolf Eike Beer2012-02-181-32/+67
| | | | | | Since we know which compiler we have we can test those OpenMP flags first that are likely to be correct. This doesn't make any difference for GNU compilers, but it should avoid useless try_compiles and output cluttering for all others.
