f3155cd Add RunCMake.Syntax test to cover argument parsing
Replace the boolean value that indicates whether an argument is unquoted
or quoted with a generalized enumeration of possible argument types.
For now "Quoted" and "Unquoted" remain the only types.
In the common case of custom command dependencies specified via full
path optimize the implementation of GetSourceFileWithOutput using a
(hash) map. This is significantly faster than the existing linear
search. In the non-full-path case fall back to the existing linear
suffix search.
* 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.
Since commit ad502502 (cmMakefile: Track configured files so we can
regenerate them, 2013-06-18) cmMakefile::ConfigureFile records the
configured file as an output file generated by CMake. The intention is
that for make and ninja we can re-run CMake when one of the files it
generates goes missing. However, files configured temporarily in
CMakeTmp directories by Check* modules do not live past the CMake
invocation.
Teach cmMakefile::ConfigureFile to skip tracking files with "CMakeTmp"
in their path, just like cmCoreTryCompile::TryCompileCode does to
avoid adding dependencies on temporary source files. In the future
we will need a more general filter to avoid recording as CMake
outputs any files that do not exist at the end of generation.
It accepted an optional argument to test for equality, but no way
to get the linker language of a particular target.
TARGET_PROPERTY provides this flexibility and STREQUAL provides
the necessary API for equality test.
Extend the CompileDefinitions test to cover accessing the
property of another target.
9cf3547 Add the INTERFACE_SYSTEM_INCLUDE_DIRECTORIES target property.
1925cff Add a SYSTEM parameter to target_include_directories (#14180)
286f227 Extend the cmTargetPropCommandBase interface property handling.
83498d4 Store system include directories in the cmTarget.
f1fcbe3 Add Target API to determine if an include is a system include.
2679a34 Remove unused variable.
Use constructs similar to those for COMPILE_OPTIONS. This is a little
different because there is a command to remove_definitions(), so
we can't populate the equivalent target property until generate-time
in cmGlobalGenerator.
Entries from the cmMakefile are processed and maintained similarly
to other include directories. The include_directories(SYSTEM)
signature affects all following targets, and all prior targets
in the same makefile.
Currently when a configured file is removed from the build directory,
running the build command will not regenerate the file. Now detect
this and will rerun cmake properly when a user issues the build
command.
AddCMakeDependFile and AddCMakeOutputFile both store as std::string
and all calling sites use std::string. So instead of creating more
temporary objects, lets just use std::strings.
This command is similar to add_definitions, in that it affects
the compile options of all targets which follow it. The implementation
is similar to the implementation of the include_directories command,
in that it is based on populating a COMPILE_OPTIONS directory property
and using that to initialize the same property on targets.
Unlike the include_directories command however, the add_compile_options
command does not affect previously defined targets. That is, in
the following code, foo will not be compiled with -Wall, but bar
will be:
add_library(foo ...)
add_compile_options(-Wall)
add_library(bar ...)

...
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.
Since commit 08cb4fa4 (Process generator expressions in the
INCLUDE_DIRECTORIES property., 2012-09-18), it is possible to use
generator expressions with the include_directories command.
As that command can also have a SYSTEM argument, ensure that the
result of using that argument with generator expressions gives a
sane result.
During configure-time, GetIncludeDirectories may be called too, for example
if using the export() command. As the content can be different, it should
be output each time then.
Otherwise, we get a separate IncludeDirectoriesEntry for each include,
and that causes unnecessary and confusing splitting in the output when
debugging the INCLUDE_DIRECTORIES property.
Historically CMake has always expanded ${} variable references in the
values given to include_directories(), link_directories(), and
link_libraries(). This has been unnecessary since general ${}
evaluation syntax was added to the language a LONG time ago, but has
remained for compatibility with VERY early CMake versions.
For a long time the re-expansion was a lightweight operation because it
was only processed once at the directory level and the fast-path of
cmMakefile::ExpandVariablesInString was usually taken because values did
not have any '$' in them. Then commit d899eb71 (Call
ExpandVariablesInString for each target's INCLUDE_DIRECTORIES,
2012-02-22) made the operation a bit heavier because the expansion is
now needed on a per-target basis. In the future we will support
generator expressions in INCLUDE_DIRECTORIES with $<> syntax, so the
fast-path in cmMakefile::ExpandVariablesInString will no longer be taken
and re-expansion will be very expensive.
Add policy CMP0019 to skip the re-expansion altogether in NEW behavior.
In OLD behavior perform the expansion but improve the fast-path
heuristic to match ${} but not $<>. If the policy is not set then warn
if expansion actually does anything. We expect this to be encountered
very rarely in practice.
Since commit e1409ac5 (Support building shared libraries or modules
without soname, 2012-04-22) CMake crashes on the code
add_library(foo SHARED foo.nolang)
because the logic to lookup the language's soname flag was moved from
cmTarget::GetLibraryNames to cmMakefile::GetSONameFlag without its check
for a NULL language. Restore the check for NULL.
Add RunCMake.Languages test to cover language error cases like this one.
In trace mode ('--trace'), any 'elseif' or 'else' commands that are
evaluated as part of a conditional block will be printed. Previously,
only the opening 'if' command of a conditional block was printed.
Add a boolean target property NO_SONAME which may be used to disable
soname for the specified shared library or module even if the platform
supports it. This property should be useful for private shared
libraries or various plugins which live in private directories and have
not been designed to be found or loaded globally.
Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and
hard-coded -install_name flags with a conditional <SONAME_FLAG> which is
expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG
definition as long as soname supports is enabled for the target in
question. Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in
rules in case third party projects still use it. Such projects would
not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be
expanded. Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well. Since
-install_name is soname on OS X, this should not be a problem if this
variable is expanded only if soname is enabled.
The Ninja generator performs rule variable substitution only once
globally per rule to put its own placeholders. Final substitution is
performed by ninja at build time. Therefore we cannot conditionally
replace the soname placeholders on a per-target basis. Rather than
omitting $SONAME from rules.ninja, simply do not write its contents for
targets which have NO_SONAME. Since 3 variables are affected by
NO_SONAME ($SONAME, $SONAME_FLAG, $INSTALLNAME_DIR), set them only if
soname is enabled.
Add cmGlobalGenerator::GenerateRuleFile to compute a generator-specific
rule file location. This will allow specific generators to override the
location of .rule files without changing the behavior of other
generators.
Teach cmMakefile::AddCustomCommandToOutput to return the cmSourceFile
instance to which the custom command is attached. Use the return value
instead of separately adding a .rule extension and searching for the
source. Mark CMake-generated .rule files explicitly with a property
instead of trusting the file extension.
Commit 328c0f65 (Simplify cmVisualStudio10TargetGenerator source
classification, 2012-03-19) introduced the first use of source
classification from cmGeneratorTarget (which originated as Makefile
generator logic) in a Visual Studio generator for handling of header
files. Fix classification of header files to match known header
extensions instead of only the HEADER_FILE_ONLY property. Make it
consistent with the "Header Files" source group.
This library type can compile sources to object files but does not link
or archive them. It will be useful to reference from executable and
normal library targets for direct inclusion of object files in them.
Diagnose and reject the following as errors:
* An OBJECT library may not be referenced in target_link_libraries.
* An OBJECT library may contain only compiling sources and supporting
headers and custom commands. Other source types that are not normally
ignored are not allowed.
* An OBJECT library may not have PRE_BUILD, PRE_LINK, or POST_BUILD
commands.
* An OBJECT library may not be installed, exported, or imported.
Some of these cases may be supported in the future but are not for now.
Teach the VS generator that OBJECT_LIBRARY targets are "linkable" just
like STATIC_LIBRARY targets for the LinkLibraryDependencies behavior.
Rename cmGlobalGenerator::GetCMakeCFG{InitDirectory => IntDir} to
have a shorter name without a typo. Add a 'const' qualifier since
the method is only for lookup and never needs to modify anything.
