This can be allowed in the next release, but it needs to have some
features present and tested such as
* Ensuring that relative paths do not appear in the generated property.
* Ensuring that paths to the source or build directories do not appear.
* Generating a check in the file for CMake 3.1 or later so that the
resulting property will be consumed.
* Ensuring that any referenced targets are part of an export set and
generating a check for them.
* INSTALL_INTERFACE and BUILD_INTERFACE content.
All of these checks are already done for INTERFACE_INCLUDE_DIRECTORIES,
but it is too late to add them for INTERFACE_SOURCES for CMake 3.1.
As the checks introduce some new error conditions, it is better to
disallow exporting fully for this case and introduce proper error
conditions later instead of policies.
Follow the pattern of checks that are made for INTERFACE_INCLUDE_DIRECTORIES.
Existence is already checked by cmSourceFile::GetFullPath. Add a check
to disallow relative paths in source directories. Otherwise code such as
target_sources(lib1 INTERFACE foo.cpp)
would fail if consumed by a target in a different directory.
Unlike the INTERFACE_INCLUDE_DIRECTORIES behavior, we don't care whether
the entry comes from an IMPORTED target or not. In the include directories
case, the directory for a non-imported target might not exist yet but
might be created. In the sources case, a file which does not yet
exist in the filesystem must be explicitly marked with the GENERATED
property.
Adjust existing tests and add a new test for the error.
Since commit v3.1.0-rc1~688^2~15 (cmTarget: Add a method to obtain list of
filenames for sources, 2014-03-17) we have code paths that lookup sources by
strings containing their own full path after normalization to the actual case
on disk. This fails in the case that a cmSourceFile has already been created
with a different case in the filename. The comparison of the directory works
because it is always normalized. Only the comparison of the file name fails.
Fix this by using a case-insensitive comparison of source file names on
platforms that do not have case-sensitive filesystems.
Extract a new method to encapsulate the requirements of evaluating
dependent-expressions, namely, propagation of the
EvaluateForBuildsystem setting, which is missing from the
getLinkedTargetsContent implementation.
Commit v3.1.0-rc1~688^2 (Genex: Only evaluate TARGET_OBJECTS to determine
target sources., 2014-03-20) introduced an error case for use of
TARGET_OBJECTS outside of the context of generating the buildsystem,
as the path to object files may be dependent on buildsystem
variables (See bug #15226).
Commit v3.1.0-rc1~314^2 (Allow INTERFACE_SOURCES to specify
$<TARGET_OBJECTS> (#14970), 2014-07-09) made it possible to
propagate such content to dependent targets.
While that commit propagated the EvaluateForBuildsystem setting
for the case of a TARGET_PROPERTY expression, as generated for
direct dependencies of a target in
cmTargetInternals::AddInterfaceEntries, it did not add propagation
for content from further transitive target dependencies, as determined
by getLinkedTargetsContent.
This reverts commit v3.1.0-rc1~557^2~2 (ClearMatches: Only clear matches
which were actually set, 2014-03-12). The optimization did not track
the match count in the same scope as the variables, allowing possible
inconsistency.
Resolve conflicts in Source/cmIfCommand.cxx, Source/cmMakefile.cxx,
and Source/cmMakefile.h by moving the changes to the new location
of the code involved.
It gets incremented while entering a loop block (e.g. foreach or while)
and gets decremented when leaving the block. Because scope borders for
example at function borders must be taken into account the counter is
put into a stack. With every new scope an empty counter is pushed on the
stack, when leaving the scope the original value is restored.
This will allow easy querying if the break command is properly nested
within a loop scope.

This commit fixes a bug where it was impossible to specify
/INCREMENTAL to Fortran projects built with Visual Studio.
The problem was due to the fact that .vfproj files expect
the value of this flag to be "linkIncremental{No,Yes},
whereas .vcproj files expect this value to be 0, 1, or 2.
The implementation of this fix adds a new data structure for
Visual Studio linker flags specific to Fortran. This can
easily be extended in the future if more such discrepencies
between C/C++ and Fortran linking are discovered.
Re-run if the input file changes or if the output file is removed.
This only works with the Makefile generators currently. The limitation
of the Ninja generator is tracked as issue #15256. The IDE
generators will need larger refactoring as they currently rely on
being able to determine the depends and output files at the start of
generate-time, which is too early for the file(GENERATE) case.

ad6ee426 Rename doing_verbatim to doing_nothing
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.
Use an explicit "$TARGET_FILE" variable instead of "$out" so that
we can have multiple output files while still only referencing the
main one in command lines.
Now that we know the year component of this VS version we
can add it to the generator name. For convenience, map
the name without the year to the name with the year.
Visual Studio 14 (2015) complains if a static character array is
declared with more than 65535 elements. This limit should be large
enough for SharedForward clients, so just hard-code that instead of
trying to compute a limit.
Teach the add_custom_command and add_custom_target commands a new
USES_TERMINAL option. Use it to tell the generator to give the command
direct access to the terminal if possible.
CMake requires both the Desktop SDK and the correct platform SDK
(Windows Phone or Windows Store) to be installed when targeting the
Windows mobile platforms. Verify that the right platform components are
installed and give a more detailed error message when something is

32922840 Refactor and seperate search path construction for find commands
The special case added by commit v2.4.0~3051 (When building CMake
itself, use the new cmake to install so that the current cmake can be
overwritten, 2004-06-09) does not make sense when cross-compiling.
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.
Manage classes of search paths in labeled containers. This removes the
need to have a seperate member variable for each type of search path, but
also allows path types to be grouped togethor in various different ways
and manipulated as subsets of the full set of search paths.
The functions for adding the various different types of paths have been
factored out into a new class, cmSearchPath. It is to be used as a helper
container class for the various find_* commands.
Prior to this commit, the set of search paths to traverse for find commands
was incrementally constructed. This change allows each group of paths, i.e.
CMakeVariablePaths, UserHintsPaths, SystemEnvironmentPaths, etc. to be
constructed and manipulated independently, and then all combined togethor.
Visual Studio 12 (2013) deprecated GetVersionEx:
warning C4996: 'GetVersionExW': was declared deprecated
in favor of either "versionhelpers.h" or VerifyVersionInfo, neither of
which exist in some of the older compilers we support. Rather than
try to port conditionally to VerifyVersionInfo, simply suppress the
warning for now.
Since commit v3.1.0-rc1~227^2~1 (De-duplicate shared library targets in
generated link lines, 2014-07-30) we de-duplicate shared library targets
on the link line. However, some toolchains will fail linking if an
executable is linking to a shared library that is not used directly and
a static library that depends on the shared one. The linker may not
keep the reference to the shared library the first time and then the
symbols needed by the static library may not be found.
Fix this by reversing the direction of the for loop that removes the
duplicate shared libraries, in order to ensure that the last occurrence
of the library is left instead of the first one.
Extend Tests/Dependency with a case covering this behavior. Create an
executable that links to a shared library and a static library but only
needs the shared library as a dependency of the static library.

b6b37e30 Makefile: Add assembly and preprocessed targets for Fortran
0842b084 Makefile: Refactor checks for lang-specific targets and export compile cmds
The logic introduced in commit v3.1.0-rc1~688^2~9 (Genex: Evaluate
TARGET_OBJECTS as a normal expression, 2014-02-26) ordered a map
by pointer value and then constructed a list of object files by
iterating over the map. This is not deterministic.
Since commit v3.1.0-rc1~688^2~5 (cmTarget: Allow any generator
expression in SOURCES property, 2014-03-18) the order produced by the
above-mentioned logic started being used for the actual list of object
files on the link line. Since it is not deterministic, spurious
re-links occur after re-running CMake simply because the order of
objects changed on the link line.
Fix this by iterating over the original vector of source files instead
of the map. This has a deterministic order.
The checks are now split into languages that are able to generate
assembly listings, languages that are able to generate preprocessed
listings, and languages that are able to export the compile commands.
For unescaped file: URLs on Windows, libcurl expects
the ANSI code page.

The cmake_autogen build step is implemented as a PRE_BUILD step
of the target currently if possible, rather than a standalone
custom target. This is to keep the number of (synthesized)
custom targets that appear in the UI low, but in some cases
it is necessary to fall back to a full custom target.
Fall back to a full custom target for the VS builds if autorcc
is used.
This reverts commit 5abfde6cb8.
The behaviors associated with implicit pulldown on variable lookup
seriously conflict with the optimizations made in these commits.
Basically, since values were copied upon variable lookup, not just on
PARENT_SCOPE, coupled with PARENT_SCOPE's behavior based on whether the
variable is in the current scope or not causes serious problems with not
storing a value for every variable at every scope.
The commit changed behavior of the following example, among other cases:
function(test_set)
set(blah "value2")
message("before PARENT_SCOPE blah=${blah}")
set(blah ${blah} PARENT_SCOPE)
message("after PARENT_SCOPE blah=${blah}")
endfunction()
set(blah value1)
test_set()
message("in parent scope, blah=${blah}")

In the case of:

Changes in commit b9aa5041 (cmLocalGenerator: Simplify GetIncludeFlags
output formatting, 2014-03-04) caused Windows Resource Compiler include
directories to be computed as relative paths in the Ninja generator.
This breaks the cmcldeps handling of include paths. The reason for the
regression is that several cmLocalGenerator::GetIncludeFlags callers
treated the fourth "bool forResponseFile" argument as if it controlled
whether include directories were a full path. It actually did control
that by accident until the above commit.
Add an explicit "bool forceFullPaths" argument to GetIncludeFlags
and thread the value through ConvertToIncludeReference as needed.
Update GetIncludeFlags call sites that really wanted to control the
forResponseFile setting to be aware of the new argument. Extend the
VSResource test to cover this case.

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.
