Most callers already have a std::string, on which they called c_str() to pass it
into these methods, which internally converted it back to std::string. Pass a
std::string directly to these methods now, avoiding all these conversions.
Those methods that only pass in a const char* will get the conversion to
std::string now only once.
As an INTERFACE_LIBRARY has no direct link dependencies, we can
short-circuit in cmGeneratorExpressionEvaluator and
in cmGlobalGenerator::CheckLocalGenerators.
As they do not generate any output directly, any generate- or install-
related code acn also be short-circuited. Many of the local generators
already do this.
Because only INTERFACE related properties make sense on INTERFACE_LIBRARY
targets, avoid setting other properties, for example via defaults.
* 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.
Commit 650e61f8 (Add a convenient way to add the includes install
dir to the INTERFACE., 2013-01-05) introduced an error case for
using the install(TARGETS) command with specified INCLUDES DESTINATION,
but no specified EXPORT set.
It is convenient to use a variable to set the various destinations
for different outputs (as KDE does), and some targets such as
executables are installed but not exported. This was triggering
the error case, but as it is a common case, remove the error.
Export the INCLUDES DESTINATION without appending to the
INTERFACE_INCLUDE_DIRECTORIES of the target itself. That way, a target
can be exported multiple times with different INCLUDES DESTINATION
without unintended cross-pollution of export sets.
This property is generated only for targets which have recorded
policy CMP0022 as NEW, and a compatibility mode is added to
additionally export the old interfaces in that case too.
If the old interfaces are not exported, the generated export files
require CMake 2.8.12. Because the unit tests use a version which
is not yet called 2.8.12, temporarily require a lower version.
Until now an unnamed component was always named "Unspecified".
Now this name is taken from the new cmake variable CMAKE_INSTALL_DEFAULT_COMPONENT_NAME,
which is initialized to "Unspecified". But it can now be set to something
project-specific, per directory

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.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
This adds the OPTIONAL option to the install(DIRECTORY) command. It
tells the installation rule that it is not an error if the source
directory does not exist. See issue #8394.
Details:
==========
- New cpack_add_component, cpack_add_component_group, and
cpack_add_install_type "commands" defined as macros in the CPack
module.
- Documentation for all of the variables and commands in the CPack module.
- Added get_cmake_property(... COMPONENTS) to CMake to ask for the
names of all components. Used in the CPack module to automatically
build component-based installers. (Set CPACK_MONOLITHIC_INSTALL to
turn off component-based installation).
- A group can declare its PARENT_GROUP, to build an arbitrary
hierarchy of groups.
- New CPack command cpack_configure_downloads, which creates an
installer that downloads only the selected components on-the-fly.
Those components marked DOWNLOADED will be separate packages
downloaded on-the-fly (or, all packages can be marked as such with the
ALL option to cpack_configure_downloads). Individual components are
compressed with ZIP at installer-creation time and
downloaded/uncompressed by the installer as needed. This feature is
only available on Windows with NSIS at the moment.
- NSIS installers can install themselves and enable the "Change"
button in Add/Remove programs, allowing users to go back and install
or remove components. This can be disabled through
cpack_configure_downloads, because it's only really useful is most of
the application's functionality is in downloaded components.
- Bug fix: automatically install everything whose COMPONENT was not
specified (it's a hidden, required group)
- Bug fix: fixed removal of components when re-running the NSIS
installer and unchecking components
- Bug fix: NSIS installers now only install/remove the minimal
number of files when re-run to update the installation (or by clicking
"Change" in Add/Remove programs)
- Add NAMELINK_ONLY and NAMELINK_SKIP to INSTALL command
- Options select a \"namelink\" mode
- cmInstallTargetGenerator selects files/link based on mode
- See bug #4419
- Imported bundles have the MACOSX_BUNDLE property set
- Added cmTarget::IsAppBundleOnApple method to simplify checks
- Document BUNDLE keyword in INSTALL command
- Updated IMPORTED_LOCATION property documentation for bundles
- Updated ExportImport test to test bundles
- Imported frameworks have the FRAMEWORK property set
- Added cmTarget::IsFrameworkOnApple method to simplify checks
- Also remove separate IMPORTED_ENABLE_EXPORTS property and just use ENABLE_EXPORTS since, like FRAMEWORK, it just represents the target type.
- Document FRAMEWORK keyword in INSTALL command.
- Updated IMPORTED_LOCATION property documentation for Frameworks
- Created cmExportFileGenerator hierarchy to implement export file generation
- Installed exports use per-config import files loaded by a central one.
- Include soname of shared libraries in import information
- Renamed PREFIX to NAMESPACE in INSTALL(EXPORT) and EXPORT() commands
- Move addition of CMAKE_INSTALL_PREFIX to destinations to install generators
- Import files compute the installation prefix relative to their location when loaded
- Add mapping of importer configurations to importee configurations
- Rename IMPORT targets to IMPORTED targets to distinguish from windows import libraries
- Scope IMPORTED targets within directories to isolate them
- Place all properties created by import files in the IMPORTED namespace
- Document INSTALL(EXPORT) and EXPORT() commands.
- Document IMPORTED signature of add_executable and add_library
- Enable finding of imported targets in cmComputeLinkDepends
EXPORTS), saves a lot of code. INSTALL(DIRECTORY) is still done the old way,
since this seems to be quite complicated
-for INSTALL(TARGETS ): also parse PUBLIC_HEADER, PRIVATE_HEADER, RESOURCE

"Unspecified" component -> if no components are used at all, no change in
behaviour, if components are used completely, no change in behaviour, since
this default will be overridden everywhere, if components where used partly,
it is now possible to install only the unspecified items (e.g. everything
which wasn't marked as "Development")

Alex
-move std::string Destination to cmInstallGenerator, since all (except
the script one) have it and add a const accessor so it can be queried
-use temporary variables in cmInstallCommand for the generators so they can be reused easier
-some more const

"imported" executable target. This can then be used e.g. with
ADD_CUSTOM_COMMAND() to generate stuff. It adds a second container for
"imported" targets, and FindTarget() now takes an additional argument bool
useImportedTargets to specify whether you also want to search in the
imported targets or only in the "normal" targets.
