Ninja: Custom Command file depends don't need to exist before building When converting custom commands for the ninja build system we need to make sure that any file dependencies that exist in the build tree are converted to phony targets. This tells ninja that these files might not exist when starting the build, but could be generated during the build. This is done by tracking all dependencies for custom command targets. After all have been written out we remove all items from the set that have been seen as a target, custom command output, an alias, or a file in the source directory. Anything that is left is considered to be a file that will be generated as a side effect of another custom command.

Ninja: Add policy to require explicit custom command byproducts 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.

Ninja: Consider only custom commands deps as side-effects (#14972) Since commit v2.8.12~248^2 (Ninja: Custom Command file depends don't need to exist before building, 2013-06-07) all explicit dependencies inside build folder were considered as possible build command side-effects and phony rules were produced for them in case they don't exist when starting to build. This is unnecessary since regular compile inputs need to exist or cmake will fail. Moreover the exception for sources having GENERATED property that can be missing is already handled by WriteAssumedSourceDependencies. This fixes unwanted phony rules for all regular source files when doing in-source build, causing Ninja not complain when such files gets missing, i.e. during development. Also this reduces number of rules in ninja.build. Now only custom command dependencies are considered as possible side-effects.

Ninja: Add policy to require explicit custom command byproducts 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.

This tells ninja that these files might not exist when starting the build, but could be generated during the build. This is done by tracking all dependencies for custom command targets. After all have been written out we remove all items from the set that have been seen as a target, custom command output, an alias, or a file in the source directory. Anything that is left is considered to be a file that will be generated as a side effect of another custom command.

Add the INTERFACE_LIBRARY target type. 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.

Ninja: Consider only custom commands deps as side-effects (#14972) Since commit v2.8.12~248^2 (Ninja: Custom Command file depends don't need to exist before building, 2013-06-07) all explicit dependencies inside build folder were considered as possible build command side-effects and phony rules were produced for them in case they don't exist when starting to build. This is unnecessary since regular compile inputs need to exist or cmake will fail. Moreover the exception for sources having GENERATED property that can be missing is already handled by WriteAssumedSourceDependencies. This fixes unwanted phony rules for all regular source files when doing in-source build, causing Ninja not complain when such files gets missing, i.e. during development. Also this reduces number of rules in ninja.build. Now only custom command dependencies are considered as possible side-effects.

Ninja: Use 'console' pool for CMake re-run if possible (#14915) The pre-defined 'console' pool is a non-buffered pool that runs with a depth of 1. CMake re-run cannot be run concurrently and it will eventually output something. A non-buffered pool allows to get it as soon as possible Also, generate the minimal required version of Ninja in the build file.

Revert "Ninja: Avoid re-running CMake on next build after regeneration" Revert commit 6fac24d7 (Ninja: Avoid re-running CMake on next build after regeneration, 2014-01-09). The files reported by the method cmMakefile::GetOutputFiles() must cause CMake to re-run only if they are missing and without considering a timestamp. Therefore they cannot be listed as outputs of the re-run rule or Ninja will re-run CMake every time because the timestamp of configure_file outputs does not change. Another solution will have to be found to the original problem.
