Compute deterministic GUIDs that are unique to the build tree by
hashing the path to the build tree with the GUID logical name.
Avoid storing them in the cache, but honor any found there.
This will allow project GUIDs to be reproduced in a fresh build
tree so long as its path is the same as the original, which may
be useful for incremental builds.
Refactor the local generator creation API to accept a
cmState::Snapshot. Adjust MakeLocalGenerator to use the 'current'
snapshot in cases where there is no parent. Create the snapshot
for subdirectories in cmMakefile::AddSubdirectory.
This means that snapshots are now created at the point of extending the tree,
as appropriate, and independently of the cmLocalGenerator and cmMakefile they
represent the state for.

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.
In commit 74de9a73 (cmGlobalGenerator: Delegate storage of enabled
languages to cmState, 2015-04-11) the original LanguageEnabled
member of cmGlobalGenerator was left behind by mistake. One use
of it in EnableLanguagesFromGenerator (for try_compile) was left,
but the member is not populated anymore. Drop the member and
teach EnableLanguagesFromGenerator to copy the list of enabled
languages from one cmState to the other.

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.

We use cmGlobalGenerator::GetDirectoryContent to avoid repeating
directory listings. However, GetDirectoryContent loads content from
disk at most once. This breaks find_library calls that occur when disk
content has changed since preceding find_library calls.
Teach cmGlobalGenerator::GetDirectoryContent to save the directory
modification time when content is loaded and re-load content if it
changes.
Create a RunCMake.find_library test with a case covering this.
Provide options to fail without blocking or to block up to a timeout.
Provide options to specify the scope containing the lock so it can be
released automatically at the end of a function, file, or process.
Extend the RunCMake.file test with cases covering the file(LOCK) command
usage and error cases.
The evaluation files must be known before cmTargetTraceDependencies
attempts to find them, but we must actually generate the files after
cmTargetTraceDependencies, as that can add to target SOURCES. The
limitation is that the generated output name must not depend on the
SOURCES of a target if the generated file is used by that target.
Mark the output files as GENERATED so that trace dependencies does
not expect them to already exist in the filesystem.
Move the invokation of ForceLinkerLanguage in the Generate logic
to after the generated file names are known. ForceLinkerLanguage
tries to determine the sources of a target (in order to determine
an already-known language) and otherwise fails to get information
about the generated file.
Test that the output of file(GENERATE) can be used as a target source
file and that accessing the target SOURCES in the name of the output
file is an error. Accessing the TARGET_OBJECTS would be a similar
error if it was legal to use that generator expression in this
context. That is not currently possible and is a different error
condition, so test the current error output as a reminder to change
the expected output if that becomes possible in the future. Test
that generated rule files resulting from cmTargetTraceDependencies
appear in the SOURCES generated in the output file.
Reject the option by default. It will be implemented on a per-generator
basis. Pass the setting into try_compile project generation. Add cache
entry CMAKE_GENERATOR_PLATFORM and associated variable documentation to
hold the value persistently.
Add a RunCMake.GeneratorPlatform test to cover basic use cases for the
option. Verify that CMAKE_GENERATOR_PLATFORM is empty by default, and
that it is rejected when the generator does not support a user setting.
No call sites pass NULL to the output argument, so take it by
reference to avoid the if(output) conditions. Propagate the
change through the TryCompile APIs that call it.
Make the virtual 'Generate' method protected. Make 'DoGenerate'
the main entry point to generation. This gives cmGlobalGenerator
a chance to do some early operations before the individual
generator-specific implementations take over.
Add a cmGlobalGenerator::SetSystemName virtual method. Call it from
cmGlobalGenerator::EnableLanguage as soon as CMAKE_SYSTEM_NAME is known.
This will give generators a chance to adapt themselves to the target
system. Pass the cmMakefile instance to the method so that the
generator can update it accordingly. Return early from EnableLanguage
if SetSystemName returns false.
Delay use of CMAKE_GENERATOR_TOOLSET until the CMakeSystem.cmake
file has been configured and loaded during the first project() or
enable_language() command. This gives the toolchain file named by
CMAKE_TOOLCHAIN_FILE a chance to set CMAKE_GENERATOR_TOOLSET. This
point is still early enough to set the generator toolset prior to
the initialization of any languages that might use the toolset.
The cmake::GeneratorToolset member variable remains an indication
of what was specified by the -T option or loaded from the cache.
It does not need to be updated based on the toolchain file setting.
The cmMakefile::TryCompile can still pass cmake::GeneratorToolset
into the inner instance because the try-compiled project will do
platform and language initialization using the CMakeSystem module
configured for the outer project.
Extend the RunCMake.GeneratorToolset test with cases that use a
toolchain file to set CMAKE_GENERATOR_TOOLSET.
Teach set_property and get_property an "INSTALL" property type to be
associated with install-tree file paths. Make the properties available
to CPack for use during packaging. Add a "prop_inst" Sphinx domain
object type for documentation of such properties.
Add a ComputeObjectMapping method to compute the object
names. It takes mapping to populate as an out-parameter so
that it can be extended in the future with parameters
relevant to generator expression evaluation.
Remove the supporting cmGeneratorTarget::AddObject method. It is
no longer needed as the container member is populated directly.
The ComputeObjectMapping method is called whenever objects are
requested from the cmGeneratorTarget. Because the Xcode generator
makes no such request, explicitly invoke the method from that
generator so that the logic of checking for bad sources in object
libraries is executed.
In a follow-up, the UseObjectLibraries usage may be replaced by a
true generator expression evaluator for TARGET_OBJECTS. That
will require generators to use cmGeneratorTarget::GetExternalObjects
which is not currently the case for Xcode and VS generators.
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.
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.
In a follow-up, the list of sources will become dependent on
the config, so check for existence in cmTarget::GetSourceFiles
instead of up-front with cmGlobalGenerator::CheckTargets().
When using link_directories() and including CMAKE_CFG_INTDIR,
one can end up with duplicate RPATHs in the binary which
install_name_tool cannot fix without corrupting the binary.
Also, the cmake_install.cmake file has been fixed to correctly
handle these generator specific variables.

C++ interfaces for querying build information is increasingly only
available at generate time through the cmGeneratorTarget class. Ensure
that the required cmGeneratorTarget instances are created. Use the
cmGlobalGenerator access API to access the relevant cmGeneratorTarget
instead of creating a temporary one on the stack.
As a new feature it does not need to participate in CMP0024.
Store cmExportBuildFileGenerator instances which correspond to the
export(EXPORT) signature in a second map which does not own the
pointers. This avoids the need to add cmExportBuildFileGenerator
and dependencies to the bootstrap system.

Teach add_custom_target to check the policy too. Extend the policy to
disallow reserved target names that we use for builtin targets like
"all".
Extend the RunCMake.CMP0037 test to cover these cases.
Drop the "Modules/CMakeVS*FindMake.cmake" files. Override the
cmGlobalGenerator::FindMakeProgram method for VS generators to use their
internal APIs to locate the build tool. Set the CMAKE_MAKE_PROGRAM as a
normal variable for use by project code, but do not cache it. This will
allow CMake and CTest to select the proper tool at build time.
Add a cmGlobalGenerator::SelectMakeProgram method to select a
caller-provided make program, the CMAKE_MAKE_PROGRAM cache entry, or a
generator-provided default. Call it from all implementations of the
GenerateBuildCommand method with the corresponding generator's default,
if any.
All cmGlobalGenerator::GenerateBuildCommand call sites that need to
produce a string now generate "cmake --build" commands. The remaining
call sites immediately pass the result to cmSystemTools::RunSingleCommand.
Avoid the intermediate string and argument parsing by directly producing a
vector of strings. Also drop the ignoreErrors argument because no call
sites remain that use it.
Create a GenerateCMakeBuildCommand method to generate a command-line
string invoking "cmake --build" for a given target and configuration.
Optionally allow the "-i" make flag and additional native options.
Refactor edit_cache tool selection to ask each global generator for its
preference. Teach the Ninja generator to always use cmake-gui because
Ninja by design cannot run interactive terminal dialogs like ccmake.
Teach the Makefile generator to use cmake-gui when also using an "extra"
generator whose IDE has no terminal to run ccmake, and otherwise fall
back to CMAKE_EDIT_COMMAND selection for normal Makefile build systems.
This change causes the GetLinkInterfaceDependentStringProperty method,
called in SetupAutoGenerateTarget, after the creation of generator
targets. In CMake 4.0, the GetLinkInterfaceDependentStringProperty
will move to the cmGeneratorTarget class, and this patch is a necessary
prerequisite to that.
In commit 18412153 (Refactor cmTarget::GetCompileDefinitions...,
2013-06-06) cmQtAutomoc was refactored to get all compile definitions
from the target instead of separately asking the target and querying the
directory-level COMPILE_DEFINITIONS property value. While the
generation process does integrate directory-level COMPILE_DEFINITIONS
into the target definitions, this did not happen until after Automoc
targets are constructed. Therefore the commit regressed use of
directory-level definitions in Automoc targets.
Factor the definition finalization logic out from the
cmGlobalGenerator::CreateGeneratorTargets method into a new
cmGlobalGenerator::FinalizeTargetCompileDefinitions method and call it
before constructing Automoc targets. This will place the
directory-level definitions into the target in time to use them for the
Automoc targets.
Extend the QtAutomoc test to cover this case.
Factor member cleanup out from cmGlobalGenerator::Configure and the
destructor into a dedicated helper to avoid duplication. This fixes
clearing of BuildExportSets between configures.

Rename the Visual Studio >= 10 generators to indicate the version year:
Visual Studio 10 => Visual Studio 10 2010
Visual Studio 11 => Visual Studio 11 2012
Visual Studio 12 => Visual Stduio 12 2013
Report the names with the year to the list of available generators so
that the cmake-gui drop-down shows the years. When selecting a
generator from the "-G" option or from an existing CMAKE_GENERATOR cache
entry, recognize names without the years for compatibility and map them
to the names with years.
Update the generator names in the cmake-generators.7 manual.
All generators now support detection of the full path to the compiler, so
require it to be so. This will allow CMake<LANG>Information.cmake and
other logic to assume the full path to the compiler tool is available.
The Makefile generators already rejected CMAKE_<LANG>_COMPILER values
that did not name an existing compiler. Extend this error message to
all generators, make it occur as early as possible, and improve the
message with advice about how to set the compiler. If the full path to
the compiler is not known, finish enabling languages with a fatal error
so configuration does not continue.
For now, allow the RC language compiler to not be a full path. Later we
will need to detect the full path to "rc" under the VS IDE.
Add a RunCMake.CompilerNotFound test to cover failure cases.
Fix the RunCMake.CompilerChange test EmptyCompiler case to work
when configuration does not continue past enable_language.
Make the API for adding targets string based so that it can easily
use cmGeneratorTarget.
Teach the cmIncludeCommand to generate the exported file at
configure-time instead if it is to be include()d.
The RunCMake.ExportWithoutLanguage test now needs a dummy header.h
file as expected error from export() is now reported after the
missing file error.
The parent commit introduced a separate "AppleClang" compiler id for
Apple's Clang distribution. Add a policy in order to support projects
that expect this compiler's id to be just "Clang". When the policy is
OLD or not set, map AppleClang back to Clang. Continue to use the
AppleClang id internally while enabling the language, but set the
CMAKE_<LANG>_COMPILER_ID after project() or enable_language() to the
compatible value for use by project code.
* The ALIAS name must match a validity regex.
* Executables and libraries may be aliased.
* An ALIAS acts immutable. It can not be used as the lhs
of target_link_libraries or other commands.
* An ALIAS can be used with add_custom_command, add_custom_target,
and add_test in the same way regular targets can.
* The target of an ALIAS can be retrieved with the ALIASED_TARGET
target property.
* An ALIAS does not appear in the generated buildsystem. It
is kept separate from cmMakefile::Targets for that reason.
* A target may have multiple aliases.
* An ALIAS target may not itself have an alias.
* An IMPORTED target may not have an alias.
* An ALIAS may not be exported or imported.
The idea is to write to a temp file which contains generator
expressions, and at generate time, evaluate the generator expressions,
and write the result to a file.
Because executables on Windows are limited in the length of command line
it is possible to use, it is common to write command line arguments to a
file instead and specify the file as a source of arguments.
This new FILE(GENERATE) subcommand allows the use of generator
expressions to create such files so that they can be used with
add_custom_command for example.
Extend the cmGlobalGenerator::GenerateBuildCommand virtual method
signature with a "projectDir" parameter specifying the top of the
project build tree for which the build command will be generated.
Populate it from call sites in cmGlobalGenerator::Build where a
fully-generated build tree should be available.
Reject the option by default. It will be implemented on a per-generator
basis. Pass the setting into try_compile project generation. Add cache
entry CMAKE_GENERATOR_TOOLSET and associated variable documentation to
hold the value persistently.
Add a RunCMake.GeneratorToolset test to cover basic "-T" option cases.
Verify that CMAKE_GENERATOR_TOOLSET is empty without -T, that -T is
rejected when the generator doesn't support it, and that two -T options
are always rejected.
