Add an option for explicit BYPRODUCTS of custom commands (#14963) A common idiom in CMake-based build systems is to have custom commands that generate files not listed explicitly as outputs so that these files do not have to be newer than the inputs. The file modification times of such "byproducts" are updated only when their content changes. Then other build rules can depend on the byproducts explicitly so that their dependents rebuild when the content of the original byproducts really does change. This "undeclared byproduct" approach is necessary for Makefile, VS, and Xcode build tools because if a byproduct were listed as an output of a rule then the rule would always rerun when the input is newer than the byproduct but the byproduct may never be updated. Ninja solves this problem by offering a 'restat' feature to check whether an output was really modified after running a rule and tracking the fact that it is up to date separately from its timestamp. However, Ninja also stats all dependencies up front and will only restat files that are listed as outputs of rules with the 'restat' option enabled. Therefore an undeclared byproduct that does not exist at the start of the build will be considered missing and the build will fail even if other dependencies would cause the byproduct to be available before its dependents build. CMake works around this limitation by adding 'phony' build rules for custom command dependencies in the build tree that do not have any explicit specification of what produces them. This is not optimal because it prevents Ninja from reporting an error when an input to a rule really is missing. A better approach is to allow projects to explicitly specify the byproducts of their custom commands so that no phony rules are needed for them. In order to work with the non-Ninja generators, the byproducts must be known separately from the outputs. Add a new "BYPRODUCTS" option to the add_custom_command and add_custom_target commands to specify byproducts explicitly. Teach the Ninja generator to specify byproducts as outputs of the custom commands. In the case of POST_BUILD, PRE_LINK, and PRE_BUILD events on targets that link, the byproducts must be specified as outputs of the link rule that runs the commands. Activate 'restat' for such rules so that Ninja knows it needs to check the byproducts, but not for link rules that have no byproducts.

Support building shared libraries or modules without soname (#13155) Add a boolean target property NO_SONAME which may be used to disable soname for the specified shared library or module even if the platform supports it. This property should be useful for private shared libraries or various plugins which live in private directories and have not been designed to be found or loaded globally. Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and hard-coded -install_name flags with a conditional <SONAME_FLAG> which is expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG definition as long as soname supports is enabled for the target in question. Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in rules in case third party projects still use it. Such projects would not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be expanded. Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well. Since -install_name is soname on OS X, this should not be a problem if this variable is expanded only if soname is enabled. The Ninja generator performs rule variable substitution only once globally per rule to put its own placeholders. Final substitution is performed by ninja at build time. Therefore we cannot conditionally replace the soname placeholders on a per-target basis. Rather than omitting $SONAME from rules.ninja, simply do not write its contents for targets which have NO_SONAME. Since 3 variables are affected by NO_SONAME ($SONAME, $SONAME_FLAG, $INSTALLNAME_DIR), set them only if soname is enabled.

cmListFileBacktrace: Refactor storage to provide efficient value semantics Since commit v3.4.0-rc1~321^2~2 (Genex: Store a backtrace, not a pointer to one, 2015-07-08) we treat cmListFileBacktrace instances as lightweight values. This was true at the time only because the backtrace information was kept in the cmState snapshot hierarchy. However, that forced us to accumulate a lot of otherwise short-lived snapshots just to have the backtrace fields available for reference by cmListFileBacktrace instances. Recent refactoring made backtrace instances independent of the snapshot hierarchy to avoid accumulating short-lived snapshots. This came at the cost of making backtrace values heavy again, leading to lots of string coying and slower execution. Fix this by refactoring cmListFileBacktrace to provide value semantics with efficient shared storage underneath. Teach cmMakefile to maintain its call stack using an instance of cmListFileBacktrace. This approach allows the current backtrace to be efficiently saved whenever it is needed. Also teach cmListFileBacktrace the notion of a file-level scope. This is useful for messages about the whole file (e.g. during parsing) that are not specific to any line within it. Push the CMakeLists.txt scope for each directory and never pop it. This ensures that we always have some context information and simplifies cmMakefile::IssueMessage. Push/pop a file-level scope as each included file is processed. This supersedes cmParseFileScope and improves diagnostic message context information in a few places. Fix the corresponding test cases to expect the improved output.
