| * CMP0037: Allow test and package targets when features are not enabledBrad King2017-10-301-0/+1
| | | | | | | | | | | | | | When CMake will not generate a test, package, or package_source target, allow projects to create their own targets with these names. Fixes: #16062
* | CMP0040: Clarify policy warning to match documentationBrad King2017-10-261-1/+1
|/ | | | | | | | | In commit v3.5.0-rc1~8^2~2 (Help: Clarify policy `CMP0040` documentation, 2016-01-28) the documentation was clarified to indicate that the target must be defined in the current directory. Do the same for the text of the policy warning itself. Fixes: #17399
* Autogen: Process GENERATED files. Add CMP0071.Sebastian Holtermann2017-07-181-1/+3
| | | | | | | | | | This lets AUTOMOC and AUTOUIC process GENERATED files which used to be ignored before. A new policy CMP0071 ensures that the old behavior of ignoring GENERATED files is enabled when the CMake compatibility version CMAKE_MINIMUM_REQUIRED is < 3.10. Closes #16186
* file(GENERATE): Add policy CMP0070 to define relative path behaviorBrad King2017-06-091-0/+3
| | | | | | | | | Previously `file(GENERATE)` did not define any behavior for relative paths given to the `OUTPUT` or `INPUT` arguments. Define behavior consistent with CMake conventions and add a policy to provide compatibility for projects that relied on the old accidental behavior. Fixes: #16786
* Add deprecation warnings for policies CMP0036 and belowBrad King2017-04-211-0/+1
| | | | | | The OLD behaviors of all policies are deprecated, but only by documentation. Add an explicit deprecation diagnostic for some policies to encourage projects to port away from setting policies to OLD.
* Use quotes for non-system includesDaniel Pfeifer2017-04-111-1/+1
| | | | | | | | | | | | | Automate with: git grep -l '#include <cm_' -- Source \ | xargs sed -i 's/#include <\(cm_.*\)>/#include "\1"/g' git grep -l '#include <cmsys/' -- Source \ | xargs sed -i 's/#include <\(cmsys\/.*\)>/#include "\1"/g' git grep -l '#include <cm[A-Z]' -- Source \ | xargs sed -i 's/#include <\(cm[A-Z].*\)>/#include "\1"/g'
* Add policy CMP0069 to enforce INTERPROCEDURAL_OPTIMIZATIONRuslan Baratov2017-03-301-1/+5
| | | | | | | | | Previously the `INTERPROCEDURAL_OPTIMIZATION` target property was honored only for the Intel compiler on Linux and otherwise ignored. In order to add support for more compilers incrementally without changing behavior in the future, add a new policy whose NEW behavior enforces the `INTERPROCEDURAL_OPTIMIZATION` property. Add flags for supported compilers and otherwise produce an error.
* Add policy CMP0068 separate install_name and RPATH settings on macOSClinton Stimpson2017-02-141-2/+6
| | | | | | | | BUILD_WITH_INSTALL_RPATH, SKIP_BUILD_RPATH, CMAKE_SKIP_RPATH and CMAKE_SKIP_INSTALL_RPATH no longer any effect on the install name of a target on macOS. Fixes: #16589
* try_compile: Add policy CMP0067 to honor language standardsBrad King2016-12-061-1/+4
| | | | | | | | | | | | | | Projects use `try_compile` to check if they will be able to compile some particular source code. When a language standard variable like `CMAKE_CXX_STANDARD` is set, then the project intends to compile source code using a compiler mode for that standard. Therefore it makes sense for `try_compile` to use that standard in the test project too. Unfortunately this was not done when support for the `CMAKE_CXX_STANDARD` variable was first implemented. Add a policy to introduce the improved behavior in a compatible way. Closes: #16456
* Simplify CMake per-source license noticesBrad King2016-09-271-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* try_compile: Add policy CMP0066 to honor CMAKE_<LANG>_FLAGS_<CONFIG>Brad King2016-06-291-1/+4
| | | | | | | | | | | | | | | | In the `try_compile` source file signature we propagate the caller's value of `CMAKE_<LANG>_FLAGS` into the test project. Extend this to propagate `CMAKE_<LANG>_FLAGS_<CONFIG>` too instead of always using the default value in the test project. This will be useful, for example, to allow the MSVC runtime library to be changed (e.g. `-MDd` => `-MTd`). However, some projects may currently depend on this not being done, so we need to activate the behavior using a policy. This change was originally made by commit v3.6.0-rc1~160^2 (try_compile: Honor CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11) but without the policy and so had to be reverted during the 3.6 release candidate cycle. Fixes #16174.
* Revise C++ coding style using clang-formatKitware Robot2016-05-161-228/+207
| | | | | | | | | | | | | Run the `Utilities/Scripts/clang-format.bash` script to update all our C++ code to a new style defined by `.clang-format`. Use `clang-format` version 3.8. * If you reached this commit for a line in `git blame`, re-run the blame operation starting at the parent of this commit to see older history for the content. * See the parent commit for instructions to rebase a change across this style transition commit.

* CMP0065: Restrict the use of CMAKE_SHARED_LIBRARY_LINK_<LANG>_FLAGSChuck Atkins2015-09-211-0/+4
| | | | | This new policy restricts the addition of the shared library link flags to executables only when the ENABLE_EXPORTS property is set to True.
* CMP0064: Fix recorded version of introduction to be 3.4Brad King2015-09-211-1/+1
| | | | | This policy was added for CMake 3.4 but accidentally recorded as 3.3. Fix this and update the RunCMake.CMP0064 test WARN case accordingly.
* if: Add "TEST <test>" conditionMatt McCormick2015-08-031-0/+3
| | | | | | | | if(TEST TestNameThatExists) will return true if a test with the name TestNameThatExists has been added with add_test. The syntax is similar to if(TARGET TargetName). Since use of "TEST" as an argument to if() could previously be interpreted as a non-keyword argument, add policy CMP0064 to treat it as a keyword as NEW behavior.
* cmPolicies: Replace unused include.Stephen Kelly2015-07-251-1/+1

* cmPolicies: Store only state that users can set.Stephen Kelly2015-07-251-1/+1
| | | | | cmPolicies::PolicyMap does not need to store the REQUIRED_ALWAYS or REQUIRED_IF_USED states as they are statically determined.
* cmPolicies: Store all statuses in a single bitset.Stephen Kelly2015-06-071-5/+2
| | | | | | | | Currently there are an optimal number of policies (64) such that there are no wasted bits. When another policy is added, the cmPolicyMap will grow from 40 bytes to 80, and occupy 45. By storing all in a single bitset, we stay under the cache line size of 64 bytes until there are 512 policies in a range.
* cmPolicies: Replace UNDEFINED bitset with WARN bitset.Stephen Kelly2015-06-061-2/+1
| | | | Might as well use the existing concept.
* Honor visibility properties for all target types (#15556)Brad King2015-05-261-0/+3
| | | | | | | | | | | | | | | | The <LANG>_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN were first merged in commit v2.8.12~322 (Merge topic 'VISIBILITY_PRESET-property', 2013-06-05) but worked only for shared libraries and executables with exports. Prior to commit v3.0.0-rc1~581^2 (GenerateExportHeader: Deprecate add_compiler_export_flags function., 2013-09-02) the add_compiler_export_flags function was used to add visibility flags to all targets. The visibility flags are useful for sources in all target types because they may be later linked into shared libraries or executables with exports. Introduce policy CMP0063 to enable them for all target types while preserving compatibility with existing projects that do not expect this.

* Revert "add_custom_command: Diagnose MAIN_DEPENDENCY limitation."Nils Gladitz2015-04-301-2/+0
| | | | | | | | | | | | This reverts commit 242c3966 (add_custom_command: Diagnose MAIN_DEPENDENCY limitation, 2015-03-09) and the follow up commit b372a99a (UseSWIG: Do not use MAIN_DEPENDENCY on custom commands, 2015-03-26). I misdiagnosed the underlying issue that prompted creation of policy CMP0057. The actual issue surfaces when a single custom command's MAIN_DEPENDENCY is listed in more than one target; this issue will have to be addressed independently.
* Link libraries by full path even in implicit directoriesBrad King2015-04-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | When CMP0003 was first introduced we wanted to link all libraries by full path. However, some projects had problems on platforms where find_library would find /usr/lib/libfoo.so when the project really wanted to link to /usr/lib/<arch>/libfoo.so and had been working by accident because pre-CMP0003 behavior used -lfoo to link. We first tried to address that in commit v2.6.0~440 (Teach find_library to avoid returning library paths in system directories, 2008-01-23) by returning just "foo" for libraries in implicit link directories. This caused problems for projects expecting find_library to always return a full path. We ended up using the solution in commit v2.6.0~366 (... switch library paths found in implicit link directories to use -l, 2008-01-31). However, the special case for libraries in implicit link directories has also proven problematic and confusing. Introduce policy CMP0060 to switch to linking all libraries by full path even if they are in implicit link directories. Explain in the policy documentation the factors that led to the original approach and now to this approach.
* Do not treat DEFINITIONS as a built-in directory propertyStephen Kelly2015-04-021-0/+2
| | | | | | | | Add policy CMP0059 to cover this change. The property has been deprecated since CMake 2.4 anyway. This will help clean up cmMakefile -- the DefineFlagsOrig member should not need to exist.
* Ninja: Add policy to require explicit custom command byproductsBrad King2015-03-201-0/+1
| | | | | | | | | | | | Add policy CMP0058 to avoid generating 'phony' ninja rules for unknown custom command dependencies. This requires projects to specify their custom command byproducts explicitly. With this requirement we no longer have to assume that unknown custom command dependencies are generated and can instead simply assume they are source files expected to exist when the build starts. This is particularly important in in-source builds. It is also helpful for out-of-source builds to allow Ninja to diagnose missing files before running custom command rules that depend on them.
* add_custom_command: Diagnose MAIN_DEPENDENCY limitation.Nils Gladitz2015-03-091-0/+2
| | | | | The new policy CMP0057 diagnoses reuse of the same MAIN_DEPENDENCY across multiple custom commands.
* try_compile: Pass linker flags into test project (#14066)Brad King2014-12-031-0/+1
| | | | | | | | | | | | Copy CMAKE_EXE_LINKER_FLAGS into the test project generated by try_compile, just like we already copy CMAKE_<LANG>_FLAGS. Add CMake Policy CMP0056 to activate this behavior in a compatible way, but do not warn by default when the policy is not set since it will affect all try_compile calls. Extend the RunCMake.try_compile test with a case covering this behavior for each policy setting.
* break: Add policy CMP0055 to check calls strictlyGregor Jasny2014-11-251-0/+1
| | | | | | Reject break() without loop scope or any arguments. Signed-off-by: Gregor Jasny <gjasny@googlemail.com>
