Check for CMAKE_COMPILER_IS_MINGW only after enabling a language when it
might actually be set. Previously this worked by accident because the
check for working compiler or a second language enabled would cause the
code path to be taken.
Store UsingMinGW as an instance member of cmGlobalNinjaGenerator so that
it is reset on each reconfigure. Otherwise cmake-gui cannot switch
between build trees for MinGW or non-MinGW tools.
Revert the refactoring by commit v2.8.11~105^2~1 (Ninja: use MinGW
generator code in EnableLanguage, 2013-03-09) and move the MinGW-
specific logic back to the "MinGW Makefiles" generator. Instead teach
the platform information modules for GNU and MSVC on Windows to set the
preferred RC compiler just before enabling the RC language. This way
we choose the RC compiler based on the C/C++ toolchain that is actually
enabled.

Extend the RunSingleCommand signature to capture stdout and stderr

to preserve existing behavior. Update all call sites to do this
so that this refactoring does not introduce functional changes.
66b641f4 Help: Add notes for topic 'add-GreenHills-MULTI-generator'
48004d9d Add a 'Green Hills MULTI' generator on Windows
051d8be1 cmLocalGenerator: Constify some cmTarget and cmGeneratorTarget arguments
Green Hills MULTI is an IDE for embedded real-time systems. The IDE's
product page can be found here:
http://www.ghs.com/products/MULTI_IDE.html
It supports cross compiling on ARM, Intel x86, and other architectures
with various operating systems. The IDE exists on Linux and Windows
host systems, but CMake will currently only generate the project files
on Windows host systems.
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.
Teach WriteUnknownExplicitDependencies to take ownership of the set of
WriteBuild outputs immediately since no other methods need the data.
This avoids re-inserting the whole set into another already populated
set.
The phony rules added by commit v2.8.12~248^2 (Ninja: Custom Command
file depends don't need to exist before building, 2013-06-07) are
circular, e.g.
build side-effect: phony side-effect
This is not diagnosed by Ninja as of version 1.5, but the dependency
does not make sense. Simply drop it and use phony rules of the form
build side-effect: phony
instead.

The Ninja build system does not support a in-file verbositiy switch.
Instead teach 'cmake --build' to extract the CMAKE_VERBOSE_MAKEFILE
setting and pass it as an optional '-v' argument to Ninja. This can
serve as a reasonable fallback.

Revert commit 7243c951 (Ninja: Don't limit custom cmd side-effects to
build folder, 2014-06-27) because it causes every custom command
dependency in the source tree to get a phony rule. For large projects
these rules get too big for Ninja to handle efficiently. While the
original change addressed a valid concern, it did not seem to occur
regularly in practice because well-behaved projects generate their
side-effects only in the build tree. Until we support explicit
specification of side-effects (CMake issue #14963), we will have to use
this as a middle-ground.
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.
Unlike with Unix Makefiles generator modifying compiler paths was not
protected with Ninja generator. It was possible to modify them in the
cache without the expected effect on the generated solution. Also
activate corresponding tests with Ninja.
Actually custom command can write wherever it wants to, such as temporary
folder or source folder, possibly violating rules that only build folder should
be affected. Therefore we should consider custom command dependency at any path
as possible side effect adding phony rule.
We avoid adding phony rules for regular source files (since the paraent
commit) so we no longer need the in-build-tree test to avoid them.
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.
It may happen that CMake include is an explicit dependency for some command,
while all CMake includes are set phony in WriteTargetRebuildManifest, this may
lead to duplicate phony generate rules which causes ninja warnings.
We need to remove implicit CMake includes in WriteUnknownExplicitDependencies.
This fixes FindCUDA ninja warnings.
Implement it in terms of the ComputeObjectFilenames virtual method
on the local generators.
Remove the reimplementation from the global generators which are
now all functionally identical.
Use the clang RemoveCStrCalls tool to automatically migrate the
code. This was only run on linux, so does not have any positive or
negative effect on other platforms.
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.
The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.
Revert commit 4a6397a7 (Ninja: Track configured files so we can
regenerate them, 2013-06-17). The files reported by the method
cmMakefile::GetOutputFiles() must cause CMake to re-run only if they are
missing and without considering a timestamp. This is not the meaning of
the implicit dependencies field so Ninja re-runs CMake too often.
Another solution will have to be found to the original problem.
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.
