* Merge branch 'revise-compiler-id-policies' into releaseBrad King2014-04-021-0/+16

| * Do not warn by default when policy CMP0025 or CMP0047 is not setBrad King2014-04-021-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These policies are triggered by the use of a particular compiler rather than outdated CMake code in a project. Avoid warning in every project that enables a language by not displaying the policy warning by default. Add variable CMAKE_POLICY_WARNING_CMP<NNNN> to control the warning explicitly; otherwise enable the warning with --debug-output or --trace. This breaks with strict policy convention because it does not provide developers with any warning about the behavior change by default. Existing projects will continue to build without a warning or change in behavior. When a developer changes the minimum required version of CMake in a project to a sufficiently high value (3.0), the project will suddenly get the new compiler id and may break, but at least the breakage comes with a change to the project rather than the version of CMake used to build it. Breaking strict policy convention is worthwhile in this case because very few projects will be affected by the behavior change but every project would have to see the warning if it were enabled by default.

* cmMakefile: make some methods take const std::string& instead of const char*Rolf Eike Beer2014-01-161-7/+11
| | | | | | | | Most callers already have a std::string, on which they called c_str() to pass it into these methods, which internally converted it back to std::string. Pass a std::string directly to these methods now, avoiding all these conversions. Those methods that only pass in a const char* will get the conversion to std::string now only once.

* | cmTarget: Don't update IMPORTED target compilation propertiesStephen Kelly2014-01-041-1/+1
|/ | | | | | The include_directories() and add_compile_options() commands should not append to the corresponding target property for IMPORTED targets. This is already the case for add_definitions().
* INTERFACE_LIBRARY: Avoid codepaths which set unneeded properties.Stephen Kelly2013-11-251-0/+8
| | | | | | | | | | | | | As an INTERFACE_LIBRARY has no direct link dependencies, we can short-circuit in cmGeneratorExpressionEvaluator and in cmGlobalGenerator::CheckLocalGenerators. As they do not generate any output directly, any generate- or install- related code acn also be short-circuited. Many of the local generators already do this. Because only INTERFACE related properties make sense on INTERFACE_LIBRARY targets, avoid setting other properties, for example via defaults.

* Refactor internal resource location APIs and initializationBrad King2013-11-121-1/+0
| | | | | | | | | | | | | | | | | | | | Rename cmSystemTools::FindExecutableDirectory to FindCMakeResources. Teach it to compute the locations of cmake, ctest, cpack, ccmake, and cmake-gui executables, and the location of CMAKE_ROOT. Provide this information from static cmSystemTools::Get<resource>() methods. Refactor code that needs these locations to use the new APIs. Teach FindCMakeResources to use the OS X system API to lookup the executable location. When running from the CMake build tree itself, leave a file in the tree that FindCMakeResources can use to read the location of the source tree. This avoids the need to compile the source tree location into a binary that may be installed and used without the source tree. Teach the QtDialog on OS X to create a "cmake-gui" symlink in the build tree next to "cmake" and the other tools, as is already done in the install tree for the application bundle. This ensures a consistent set of executables are available in one directory.

| * Add automatic uic invocation for Qt.Stephen Kelly2013-10-241-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | The source files are already processed by cmQtAutomoc to look for moc includes, so extend that to also look for ui_ includes and find corresponding .ui files to process. This replaces the need to invoke qt4_wrap_ui(). As the ui files are not likely to be part of the SOURCES of the target, store the options associated with them separately in the cmMakefile for querying during the autogen run.
* | Drop compatibility with CMake < 2.4Brad King2013-10-231-42/+9
|/ | | | | | | | | | | | Drop all behavior activated by setting CMAKE_BACKWARDS_COMPATIBILITY to a value lower than 2.4, and generate an error when projects or the user attempt to do so. In the error suggest using a CMake 2.8.x release. Teach cmake_minimum_required to warn about projects that do not require at least CMake 2.4. They are not supported by CMake >= 3.0. Replace the documentation of CMAKE_BACKWARDS_COMPATIBILITY with a reference to policy CMP0001.
* Add Lua-style long brackets and long comments to CMake languageBrad King2013-10-171-0/+6
| | | | | | | | | | | | | | | | | Teach the CMake language parser to recognize Lua-style "long bracket" arguments. These start with two '[' separated by zero or more '=' characters e.g. "[[" or "[=[" or "[==[". They end with two ']' separated by the same number of '=' as the opening bracket. There is no nesting of brackets of the same level (number of '='). No escapes, variable expansion, or other processing is performed on the content between such brackets so they always represent exactly one argument. Also teach CMake to parse and ignore "long comment" syntax. A long comment starts with "#" immediately followed by an opening long bracket. It ends at the matching close long bracket. Teach the RunCMake.Syntax test to cover long bracket and long comment cases.
* Drop builtin property documentationBrad King2013-10-161-234/+3
| | | | | | Drop all DefineProperty calls for non-chained properties. Drop the documentation from the chained ones. The documentation for all properties is now in Help/prop_*/*.rst files.
* Drop CMAKE_STRICT modeBrad King2013-10-151-15/+0
| | | | | | | With our modern development workflow it is less likely a property will be added to C++ code without documentation. This mode only existed to support the DocTest which had very limited coverage of the properties anyway.
* Add the INTERFACE_LIBRARY target type.Stephen Kelly2013-10-071-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | This target type only contains INTERFACE_* properties, so it can be used as a structural node. The target-specific commands enforce that they may only be used with the INTERFACE keyword when used with INTERFACE_LIBRARY targets. The old-style target properties matching LINK_INTERFACE_LIBRARIES_<CONFIG> are always ignored for this target type. The name of the INTERFACE_LIBRARY must match a validity generator expression. The validity is similar to that of an ALIAS target, but with the additional restriction that it may not contain double colons. Double colons will carry the meaning of IMPORTED or ALIAS targets in CMake 2.8.13. An ALIAS target may be created for an INTERFACE library. At this point it can not be exported and does not appear in the buildsystem and project files are not created for them. That may be added as a feature in a later commit. The generators need some changes to handle the INTERFACE_LIBRARY targets returned by cmComputeLinkInterface::GetItems. The Ninja generator does not use that API, so it doesn't require changes related to that.

| * Use first custom command for the same output (#14446)Brad King2013-09-301-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In buggy code like add_custom_command( OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/out.h MAIN_DEPENDENCY ${CMAKE_CURRENT_SOURCE_DIR}/out.h.in ...) add_custom_command( OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/out.h ...) that has more than one rule to generate the same output CMake has always used the first rule. However, since commit 2268c41a (Optimize custom command full-path dependency lookup, 2013-08-06) we update the map from output to cmSourceFile for every rule generating an output, effectively keeping the last command instead of the first. Fix this regression by checking for each map update if the output already has an entry. If so, keep only the original entry. The VS 8 generator triggers this with a special case for generate.stamp rules that differ between ZERO_CHECK and normal targets, so do not warn for now. Leave a TODO comment for warning in the future.

The intention is that for make and ninja we can re-run CMake when one of the files it generates goes missing. However, files configured temporarily in CMakeTmp directories by Check* modules do not live past the CMake invocation. We have to also track input files to the configure command. In theory the input to a configure command could it self be a file that is going to be deleted later (output from a custom command or configure_file).
