Implement generator toolset selection (cmake -T) for VS >= 10 by setting
the PlatformToolset. Extend the RunCMake.GeneratorToolset test case to
verify CMAKE_GENERATOR_TOOLSET when the generator supports -T.
Since commit 485a940e (VS: Simplify MSVC version reporting, 2012-08-23)
all MSVC version information is detected during the compiler id step
from the actual compiler invoked by generated build systems rather than
hard-coded in VS generators. Therefore we can set the PlatformToolset
in VS >= 10 project files and support toolsets from other VS versions.
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.

This is both a short form of using a TARGET_DEFINED expression
together with a TARGET_PROPERTY definition, and a way to strip
non-target content from interface properties when exporting.
Use a trailing slash to reference a directory. Require that a list
of associated files be specified to select from within the directory.
One may simply use DATA{Dir/,REGEX:.*} to reference all files but
get a directory passed on the command line.
Add a Module.ExternalData test to verify data retrieval and test
argument DATA{} references.
Add a RunCMake.ExternalData test to verify error handling and automatic
transformation of a raw data to a content link and staged object.
6063fef Output include directories as LOG messages, not warnings.
aa66748 Specify the target whose includes are being listed.
d70204a Only output includes once after the start of 'generate-time' when debugging.
0d46e9a Store includes from the same include_directories call together.
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.
This new expression allows checking how a policy was set when a target
was created. That information is only recorded for a subset of policies,
so a whitelist is used.
This allows a dependee to inform a target that it should have its
POSITION_INDEPENDENT_CODE property set to ON, or OFF. The value of
the POSITION_INDEPENDENT_CODE property, if set, must be consistent
with any INTERFACE_POSITION_INDEPENDENT_CODE properties on dependees.
Add a test covering the consistency checks on platforms where they run.
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 $<>. If the policy is not set then warn
if expansion actually does anything. We expect this to be encountered
very rarely in practice.
This command works only when building projects using the same
architecture as the running CMake binary. Since it was introduced
CMake has learned macro() and function() to add commands, and the
execute_process() command to launch advanced external computations.
Add a RunCMake.load_command test to verify the warning appears.
It should be possible for example to do this:
"$<AND:${FOO},$<BOOL:${TGT}>,$<BOOL:$<TARGET_PROPERTY:${TGT},PROP>"
such that it works simliarly to the C code:
if (foo && tgt && tgt->prop())
{
}
The example of generator expression code is a little bit contrived as
it could be written other ways with the same functionality. Nevertheless,
as these cases already work and are intentional, test for them.
This fixes a regression introduced in commit 290e92ad (Move
GetIncludeDirectories to cmGeneratorTarget, 2012-09-16) which loops over
cmGeneratorTargets before they get created, so the container is empty.
Otherwise the comma is treated as plain text by ParseContent.
$<STREQUAL:,> should be valid and true.
$<STREQUAL:,something> should be valid and false.
$<STREQUAL:,,> should be non-valid as it is 3 parameters.
$<STREQUAL:something,,> should be non-valid as it is 3 parameters.
Additionally, this allows reporting the correct error for other
expressions. For example $<TARGET_PROPERTY:,> should be invalid
because it has an empty target and empty property. It shouldn't
attempt to read the property ',' on the 'implicit this' target.
The expressions may be parsed and then cached and evaluated multiple
times. They are evaluated lazily so that literals such as ',' can be
treated as universal parameter separators, and can be processed from
results without appearing literally, and without interfering with the
parsing/evaluation of the entire expression.
This expression evaluates to '1' or '0' to indicate whether the build
configuration for which the expression is evaluated matches tha named
configuration. In combination with the "$<0:...>" and "$<1:...>"
expressions this allows per-configuration content to be generated.
Add generator expressions that combine and use boolean test results:
$<0:...> = empty string (ignores "...")
$<1:...> = content of "..."
$<AND:?[,?]...> = '1' if all '?' are '1', else '0'
$<OR:?[,?]...> = '0' if all '?' are '0', else '1'
$<NOT:?> = '0' if '?' is '1', else '1'
These will be useful to evaluate (future) boolean query expressions and
condition content on the results. Include tests and documentation.
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block. This is no longer the preferred style.
Run the following shell code:
for c in else endif endforeach endfunction endmacro endwhile; do
echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed
Previously CMake silently accepted the empty string and added a bogus
dependency on the current directory. Instead warn about the empty file
name and ignore it. We cannot make this an error because there may be
existing projects that accidentally depend on the old behavior.
Add a RunCMake.include test to cover this case.
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.
Add "RunCMake.include_external_msproject" test to use the TYPE, GUID, and
PLATFORM options to include_external_msproject. Since projects with
custom types and platforms cannot be loaded without special VS plugins
validate the results by directly parsing the generated solution (.sln).

Look for a <SubTest>-check.cmake script and load it to check side
effects of the sub test. Provide it with the test source and build tree
paths in variables. Check for a failure message in a result variable.
Since commit ed1ea24c (Fix INSERT to allow inserting to empty list,
2006-05-15) the list command allows insertion into an empty list at
index 0. Fix rejection of insertion at non-zero (negative) indices to
present an error message instead of crashing.
While at it, fix the error message of the GET and REMOVE_AT operations
when the list is empty to not present a bogus allowed range.
Add a "RunCMake.list" test to cover failure cases on empty lists.
Teach the RunCMake.ObjectLibrary test to verify that languages used in
an OBJECT library are propagated to targets that use it so that the
languages can be included in link analysis.
Add "RunCMake.ObjectLibrary" test to verify that unsupported use cases
are rejected with errors:
* An OBJECT library may not reference another object library
* An OBJECT library may not be referenced in target_link_libraries
* An OBJECT library may not contain non-compiling sources
* An OBJECT library may not have pre/post build/link commands
* An OBJECT library may not be installed, exported, or imported
Also verify that invalid $<TARGET_OBJECTS:...> expressions are
diagnosed.
The CMakeCommands.build_command test performs output/error checking
so move it over to RunCMake to re-use the generalized infrastrucure.
This is the only test left using Tests/CMakeCommands/CMakeLists.txt
so remove it.
The CMakeOnly directory added by commit 9a20abf0 (Add infrastructure for
CMake-only tests, 2012-01-11) was sufficient only for tests that always
run CMake to successfully configure a project. Later commit eeaaffcb
(find_package: Test error and warning messages in failure cases,
2012-02-28) added a sample test that covers failure cases.
Generalize the above to create new "RunCMake" test infrastructure that
can run CMake multiple times for a single project with different
variations and check for expected result/stdout/stderr. Allow for both
successful and failing CMake project configuration cases. This will be
useful to test error messages and failure behavior.
