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.
Pass the CMAKE_TEST_MAKEPROGRAM, if any, to each test at CMake time in
the CMAKE_MAKE_PROGRAM cache entry. Pass the CMAKE_TEST_MAKEPROGRAM
into the ExportImport, Fortran, and MacRuntimePath tests so that they
may do the same for the nested project configurations.
Now "ctest --build-and-test" can get the make program from the test
build tree cache, so drop the explicit --build-makeprogram.
Fix the condition that adds the test to check CMAKE_TEST_GENERATOR
rather than the tools used to build CMake. Drop the test on Ninja
because the generator does not support subproject generation anyway.
Stop using the general build_generator_args and pass the
--build-generator options explicitly. Also pass --build-makeprogram
explicitly when CMAKE_TEST_MAKEPROGRAM is available because there is no
CMakeCache.txt in the test project subdirectory from which to pick up
the make program.
Create a CTEST_TEST_DEVENV variable that is set to the
CMAKE_MAKE_PROGRAM used for Visual Studio 7, 8, and 9. It will always
be either "devenv" or "VCExpress", and not "MSBuild". Add the
VSExcludeFromDefaultBuild test only when this variable is set, and use
its value as the --build-makeprogram value.
More work will be needed later to restore the test on VS 10 and above
when devenv is available, but this is the simplest approach for now.
The test is only enabled on VS 10 and above, where the generators now
select for "ctest --build-and-test" the MSBuild tool by default.
Simplify the test configuration by dropping the --build-makeprogram
option and all the logic needed to compute its value. The test will
automatically use MSBuild.
The --build-options option consumes all following arguments until either
--build-target or --test-command. Fix the logic to allow this to be
zero options.
GenerateBuildCommand now knows how to lookup CMAKE_MAKE_PROGRAM or
choose a generator-provided default build tool. Therefore the
--build-makeprogram can now be optional and simply override the
default selection when provided.
Note that with --build-nocmake we now need to load the cache in order to
make the CMAKE_MAKE_PROGRAM entry available to GenerateBuildCommand.
Code paths that look up CMAKE_MAKE_PROGRAM from the cache only to
pass it to Build, which only passes it to GenerateBuildCommand,
no longer need to do so. GenerateBuildCommand now knows how to
look up CMAKE_MAKE_PROGRAM in the cache when no explicit value
is given, so simply pass 0 now.
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.
Historically these were both added for the Makefile and Visual Studio
generators, respectively. Later the VS generators started using the
CMAKE_MAKE_PROGRAM cache entry to find the IDE build tool, and the
CMAKE_BUILD_TOOL was simply set as an alias.
Fix the documentation to explain that CMAKE_MAKE_PROGRAM is the modern
variable and that CMAKE_BUILD_TOOL is the compatibility alias, not the
other way around. Replace uses of CMAKE_BUILD_TOOL with
CMAKE_MAKE_PROGRAM in CMake-provided modules. Nothing needs to lookup
CMAKE_BUILD_TOOL in the cache, so simply set it as a normal variable.
Some extra options are for "ctest --build-and-test" directly, and others
are values for "--build-options". Split these two roles out into two
separate variables and update existing uses.
Use "cmake --build" to drive the "install" target from the CMake build
tree itself. This avoids using the heavier "ctest --build-and-test"
just to run the native build tool to drive installation.
Run the bootstrap script through "cmake -P" instead of
"ctest --build-and-test" so that we do not need to abuse
the --build-makeprogram option of the latter.
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.
This avoids requiring cmGlobalGenerator::GenerateBuildCommand to produce
a string so that it can be later refactored to produce a vector with no
quoting or escaping. It also makes the ctest_build command match what
"ctest -T Build" would run in a build tree configured with the new
build_command() command behavior. It also ensures that the native build
tool used matches that selected by the configuration of the tree to be
built.
Re-implement the build_command() command to use "cmake --build" instead
of generating a native build tool invocation directly. This command
will internally invoke the proper native build tool.
This avoids requiring cmGlobalGenerator::GenerateBuildCommand to produce
a string so that it can be later refactored to produce a vector with no
quoting or escaping. It will also allow us to later teach CMake to
delay the decision about which build tool to invoke until after the
project build system is generated to disk. For example, on Visual
Studio 10 and above the preferred command-line tool is MSBuild, but we
need to fall back to devenv if the .sln has Intel Fortran .vfproj files.
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.
This is a virtual method that is overridden by every generator
subclass. The base class implementation should never be called,
so replace it with a dummy implementation.

Just as
set(VAR "")
sets VAR to an empty string in the current scope, the code
set(VAR "" PARENT_SCOPE)
is documented to set the variable to an empty string in the parent
scope. Fix the implementation to make it so.
The code "set(VAR PARENT_SCOPE)" unsets VAR in the parent scope.
Implement this case explicitly next to where "set(VAR)" is explicitly
handled to unset VAR in the current scope.
Since commit 7d47c693 (Drop compatibility with CMake < 2.4, 2013-10-08)
we no longer need to use the configure_file IMMEDIATE option to support
compatibility modes less than 2.0.
