Brad King 4fd5342956 CMake: Add -T option to choose a generator toolset
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.

Patrick Gansterer 5170a8800f Make cmGlobalGenerator::GetDocumentation() a static function
Making the function static allows us to call it directly,
without creating and removing an instance of the generator.

Stephen Kelly bd34963002 Refactor generation of shared library flags
CMAKE_SHARED_LIBRARY_<lang>_FLAGS has flags on various platforms for a
variety of purposes that are correlated with shared libraries but not
exclusive to them.  Refactor generation of these flags to use new
purpose-specific platform variables

  CMAKE_<lang>_COMPILE_OPTIONS_DLL
  CMAKE_<lang>_COMPILE_OPTIONS_PIC
  CMAKE_<lang>_COMPILE_OPTIONS_PIE

Activate the DLL flags specifically for shared libraries.  Add a new
POSITION_INDEPENDENT_CODE target property to activate PIC/PIE flags, and
default to true for shared libraries to preserve default behavior.
Initialize the new property from CMAKE_POSITION_INDEPENDENT_CODE to
allow easy global configuration in projects.

Although the default behavior is unchanged by this refactoring, the new
approach ignores CMAKE_SHARED_LIBRARY_<lang>_FLAGS completely.  We must
leave it set in case projects reference the value.  Furthermore, if a
project modifies CMAKE_SHARED_LIBRARY_<lang>_FLAGS it expects the new
value to be used.  Add policy CMP0018 to handle compatibility with
projects that modify this platform variable.

Add a PositionIndependentCode test on platforms where we can get
meaningful results.

Brad King ca39c5cdd1 Optionally allow IMPORTED targets to be globally visible
Consider the case motivating commit e01cce28 (Allow add_dependencies()
on imported targets, 2010-11-19).  An imported target references a file
generated at build time by a custom target on which it depends.  Had the
file been built directly using add_library or add_executable its target
name would have been visible globally.  Therefore the imported target
representing the file should be globally visible also.

Teach the IMPORTED signature of add_(executable|library) to accept a new
"GLOBAL" option to make the imported target visible globally.

Brad King c83a834d29 try_compile: Allow only languages loaded in caller (#11469)
During a try_compile cmGlobalGenerator::EnableLanguage uses results from
the outer project.  Reject attempts to enable languages in the test
project that are not "ready" in the outer project.  Mark a language as
"ready" when all its information has been loaded and we are ready to
generate build rules.

This also avoids infinite recursion introduced by commit 295b5b60 (Honor
CMAKE_USER_MAKE_RULES_OVERRIDE in try_compile, 2010-06-29) for projects
that set CMAKE_USER_MAKE_RULES_OVERRIDE to a file that uses try_compile.
The file is loaded along with the information for a given langauge so
the language is not yet "ready".

e6ac0aa Add FOLDER target property, for IDEs (#3796)
2010-09-08 11:08:05 -04:00
David Cole e6ac0aacf6 Add FOLDER target property, for IDEs (#3796)
This work was started from a patch by Thomas Schiffer.
Thanks, Thomas!

See the newly added documentation of the FOLDER target
property for details.

Also added global properties, USE_FOLDERS and
PREDEFINED_TARGETS_FOLDER. See new docs here, too.

By default, the FOLDER target property is used to organize
targets into folders in IDEs that have support for such
organization.

This commit adds "solution folder" support to the Visual
Studio generators. Currently works with versions 7 through
10.

Also, use the new FOLDER property in the ExternalProject
test and in the CMake project itself.

Brad King 41a608a75d Fix rule hash persistence file generation
We store custom command rule hashes in CMakeFiles/CMakeRuleHashes.txt
persistently across CMake runs.  When the rule hash changes we delete
the custom command output file and write a new hash into the persistence
file.

This functionality was first added by the commit 'Introduce "rule
hashes" to help rebuild files when rules change.' (2008-06-02).
However, the implementation in cmGlobalGenerator::CheckRuleHashes kept
the file open for read when attempting to rewrite a new file.  On
Windows filesystems this prevented the new version of the file from
being written!  This caused the first set of rule hashes to be used
forever within a build tree, meaning that all custom commands whose
rules changed would be rebuilt every time CMake regenerated the build
tree.

In this commit we address the problem by splitting the read and write
operations into separate methods.  This ensures that the input stream is
closed before the output stream opens the file.

David Cole 0b38bb4c53 Fix issue #2336 - honor the -C arg to ctest. Honor it for all stages of running -D dashboards from the command line and running ctest_configure, ctest_build and ctest_test commands in -S scripts. Also, allow a script to change it by setting the CTEST_CONFIGURATION_TYPE variable: allows for multiple configuration build/test cycles within one script. Add a new signature for the cmake command build_command that accepts CONFIGURATION as one argument. The original build_command signature is still there, but now marked as deprecated in the documentation. Of course... also add CTestConfig tests to verify that -C is honored for -D dashboards and -S scripts. 2009-12-04 12:09:01 -05:00
Brad King 9000b5a4de Avoid non-root copies of root-only targets
In cmGlobalGenerator::GetTargetSets we collect targets from all local
generators in a tree or subtree corresponding to a project() command.
Some targets, such as ALL_BUILD, are duplicated in each subdirectory
with a project() command.  For such targets we should keep only the copy
for the top-most (root) local generator.

Previously this filtering was done in each VS IDE generator, but it is
easier to do it in one place when the targets are first encountered.
This also fixes bad ALL_BUILD dependencies generated for VS 7.0 because
the cmGlobalVisualStudio7Generator::WriteTargetDepends method was not
filtering out duplicates.  Now we avoid duplicates from the start.

Brad King 80c947b397 No /fast targets in try_compile project mode
The try_compile command builds the cmTryCompileExec executable using the
cmTryCompileExec/fast target with Makefile generators in order to save
time since dependencies are not needed.  However, in project mode the
command builds an entire source tree that may have dependencies.
Therefore we can use the /fast target approach only in one-source mode.

Brad King 73de2362dd Fix recursive try_compile calls
When building an entire source tree with try_compile instead of just a

of language-initialization results from the outer-most project into any
number of try-compile levels.

Brad King a232dbe8d2 BUG: Fix Xcode linker language
Xcode does not seem to support direct requests for using the linker for
a particular language.  It always infers the linker using the languages
in the source files.  When no user source files compile with target's
linker language we add one to help Xcode pick the linker.

A typical use case is when a C executable links to a C++ archive.  The
executable has no C++ source files but we need to use the C++ linker.

This simplifies computation of custom command rule hashes to hash

Unfortunately this will change the hashes of existing build trees from

necessary so that in the future we can make optional adjustments to
custom command lines at generate time without changing the hashes every
time the option is changed.
