* ExternalProject: Add policy CMP0114 to refine step target dependenciesBrad King2020-09-141-0/+85
| | | | | | | | | | | | | | | | | | | | | | | | `ExternalProject_Add_StepTargets` and `INDEPENDENT_STEP_TARGETS` have some limitations and lack some sanity checks. They can cause confusing build systems to be generated. The basic problems are: * The notion of step independence is attached to the step target rather than the step itself. * The custom commands implementing the steps are duplicated in the step targets and the primary targets. This can cause races. It is also incompatible with the Xcode "new build system". Fix this by introducing policy CMP0114 to change the way step target dependencies are handled. Define independence from external dependencies as a property of each individual step regardless of whether there is a target for it. Add dependencies among the primary target and the step targets such that each custom command only appears in one target. When some steps are disconnected from the primary target, add step targets for the steps commonly depended upon so that there is a place to hold their custom commands uniquely. Fixes: #18663
* Makefile: Add policy CMP0113 to avoid duplication of custom commandsBrad King2020-09-081-0/+43
| | | | | | | | | | | | | | | | | Do not attach a custom command to a target if it is already attached to one of the target's dependencies. The command's output will be available by the time the target needs it because the dependency containing the command will have already been built. This may break existing projects that do not properly mark non-created outputs with the `SYMBOLIC` property. Previously a chain of two custom commands whose intermediate dependency is not created would put both commands in a dependent project's Makefile even if the first command is also in its dependency's Makefile. The first command would run twice but the build would work. Now the second command needs an explicit `SYMBOLIC` mark on its input to tell CMake that it is not expected to exist. To maintain compatibility with projects that left out the mark, add a policy activating the behavior.
* GenEx: Remove unneeded dependencies from target info queriesRobert Maynard2020-09-011-0/+39
| | | | | | | | | | Only generate a graph dependency between a custom command and a target when the custom command queries for the file path of an artifact of the target. This makes generator expressions such as `TARGET_FILE_DIR` behave the same way as `TARGET_PROPERTY` which never generated a graph dependency.
* cmTarget: Raise error if imported target location is not setRaul Tambre2020-08-211-0/+20
| | | | | | | | Previously we would synthesize <TARGET_NAME>-NOTFOUND as the location. This would then end up on the link line and cause build failures. Policy CMP0110 is added to control this behaviour. Fixes #19080, #19943.
* add_test: Allow special characters in test name (w/ policy CMP0110)Deniz Bahadir2020-08-121-0/+24
| | | | | | | | | | | | | | Restore the change from commit f84af8e270 (add_test: Allow special characters in test name, 2020-05-16, v3.18.0-rc1~142^2) that had to be reverted by commit f84af8e270 (add_test: Allow special characters in test name, 2020-05-16, v3.18.0-rc1~142^2) for compatibility. Add policy CMP0110 to make the change in a compatible way. Also, support even more characters than before by generating the test scripts using bracket arguments around the test names.

* Modules/Documentation: removeBen Boeckel2020-04-221-0/+19
| | | | | | | | | | | | This is an old module from when VTK and other Kitware projects drove the addition of commands and modules into CMake itself. Modern VTK doesn't need this module and it can be ignored. This module is kept around so that the ancient VTK versions which use it are not broken by it. VTK itself stopped using the module in 2012 and the last usage by an example in VTK was removed in 2020. Fixes: #20591

* CUDA: Add CUDA_ARCHITECTURES target propertyRaul Tambre2020-04-151-0/+31
| | | | | | | | | | | Simplifies CUDA target architecture handling. Required for Clang support as Clang doesn't automatically select a supported architecture. We detect a supported architecture during compiler identification and set CMAKE_CUDA_ARCHITECTURES to it. Introduces CMP0104 for backwards compatibility with manually setting code generation flags with NVCC. Implements #17963.

| * Help: Document that <PackageName>_ROOT applies to config packages tooCraig Scott2019-10-271-3/+3
| | | | | | | | | | | | | | | | | | The original intent of <PackageName>_ROOT may have been for it to apply only to Find modules, but the implementation of the find_package() command treats modules and config packages the same. Both result in a <PackageName>_ROOT variable being pushed onto the stack of package roots. A config package can also call other find_...() commands, the behavior doesn't apply just to find modules.

| * | Android: ensure PIE behavior is consistent regardless CMP0083 policyMarc Chevrier2019-06-191-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | In commit c4b4d8b3a6 (POSITION_INDEPENDENT_CODE: Manage link flags for executables, 2018-10-02, v3.14.0-rc1~395^2) we accidentally removed our Android-specific logic for PIE under the CMP0083 OLD behavior.

* | MSVC: Do not add /W3 to CMAKE_<LANG>_FLAGS by defaultBrad King2019-04-191-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We do not add default warning flags on other compilers, and having a warning flag in the default flags makes it hard for projects to customize the warning level. They need to use string processing to remove `/W3` from `CMAKE_{C,CXX}_FLAGS`. Therefore we should drop it. However, projects may be using string processing to replace `/W3` with another flag, so we cannot simply drop it. Add a policy to drop it in a compatible way. Fixes: #18317
* | MSVC: Add abstraction for runtime library selectionBrad King2019-04-171-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace our hard-coded defaults for `/MD` and `/MDd` with a first-class abstraction to select the runtime library from an enumeration of logical names. We've long hesitated to do this because the idea of "runtime library selection" touches on related concepts on several platforms. Avoid that scope creep by simply defining an abstraction that applies only when targeting the MSVC ABI on Windows. Removing the old default flags requires a policy because existing projects may rely on string processing to edit them and choose a runtime library under the old behavior. Add policy CMP0091 to provide compatibility. Fixes: #19108

* | export: Disable PACKAGE mode user package registry by defaultRobert Maynard2019-03-151-0/+27
| | | | | | | | | | | | | | The user package registry populated by the `export()` command causes side effects outside the build and source directories. Such effects should be opt-in rather than op-out. Introduce a policy to change default behavior of `export(PACKAGE)` to do nothing.
