Robert Maynard f73718c9b8 Features: Enable writing of MSVC compiler feature header.
Notes:
VS2015 and above are the only MSVC versions to support cxx_final, so remove
usages from the tests, and instead only test for cxx_override.

VS2012 and above to conform to cxx_decltype_incomplete_return_types
proposal, but without support for auto return types the dcl.type.simple
example in the proposal doesn't compile.

VS2013 and above to conform to the updated cxx_contextual_conversions proposal,
but VS2010 and above pass the test.

Compilers such as MSVC have no explicit flags to enable C++11 mode,
it just is always on. So only run the link tests with compilers that require
a flag to specify the language version.

Clinton Stimpson 9a8ab86645 Encoding: Modify tests to work using non-ascii paths.
For complex*, CustomCommand and OutDir tests, non-ascii paths
are avoided in test code by using relative paths, and setting
the working when running the test.  This also avoids the
need to internationalize the test code.

For RunCMake.GeneratorExpression, use a UTF-8 encoding in
file(STRINGS) to retrieve the compiled absolute path correctly.

Stephen Kelly c13656e717 Features: Test nullptr as a side-effect activation of static_assert.
Because not all compilers under test support the existing 'activation
features', add another test to ensure that compilers which support
both static_assert and nullptr behave as expected in this test.

Stephen Kelly 3e34e8331a Features: Test feature propagation with more-common features.
The purpose of the feature listing in these tests is to make other
features from the same feature set (eg "C++11 features") available.

The compilers under test until now have supported these 'activation
features', but MSVC does not.  Use the cxx_static_assert feature
instead to activate the feature set.

Stephen Kelly b3e86f4e97 Features: Test an expectation of whether OVERRIDE_CONTROL is expected
The tests below test the presence of both cxx_final and cxx_override,
only one of which is supported by MSVC.  The test is in part intended
to verify that the COMPILE_FEATURES genex supports multiple arguments
and allows users to define names for groups of features (Clang already
calls cxx_final and cxx_override 'override control' as a group).  Keep
the test, and allow the expectation to be set as appropriate.

Brad King dd089e08b5 install: Allow absolute EXPORT destination with relative targets (#15258)
When install(EXPORT) is given an absolute destination we cannot compute
the install prefix relative to the installed export file location.
Previously we disallowed installation of targets in such exports with a
relative destination, but did not enforce this for target property
values besides the location of the main target file.  This could lead to
broken installations when the EXPORT is installed to an absolute path
but usage requirements are specified relative to the install prefix.

Since an EXPORT installed to an absolute destination cannot be relocated
we can just hard-code the value of CMAKE_INSTALL_PREFIX as the base for
relative paths.  This will allow absolute install(EXPORT) destinations
to work with relative destinations for targets and usage requirements.

Extend the ExportImport test with a case covering this behavior.

Brad King ce331bab92 find_library: Fix repeat call after changing directory content (#15293)
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.

Stephen Kelly e134805666 Export: Disallow export of targets with INTERFACE_SOURCES
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.
2014-11-29 12:24:59 +01:00
Stephen Kelly bb5905bb13 cmTarget: Don't allow relative paths in INTERFACE_SOURCES
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.

Stephen Kelly 672f1001c0 Genex: Fix evaluation context propagation for TARGET_OBJECTS.
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.

Stephen Kelly 26e98c34dc file(GENERATE): Re-run cmake when appropriate.
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.

Brad King 557aef0b94 ExternalProject: Add options to specify BYPRODUCTS (#14963)
The external project's build process may generate byproducts on which
other rules in the driving project's build later depend.  Provide a way
for the driving project to specify what byproducts it expects to be made
available by the custom commands that drive the external project.

Brad King e15a7075b5 Add an option for explicit BYPRODUCTS of custom commands (#14963)
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.

Stephen Kelly b80557c7bd file(GENERATE): Evaluate early to allow generating source files
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.

Daniele E. Domenichelli 4db31095e5 Fix link line order when shared libraries are de-duplicated
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.
