Files generated by `install(EXPORT)` and `export_library_dependencies()`
may be installed with packages and consumed by dependents. In order to
avoid re-building dependents only because the version of CMake changed,
drop the CMake version from the export file content.
Drop our `HaveExportedObjects` check before dumping exports for an
object file. It is possible for only a subset of needed symbols to have
explicit markup, and re-exporting the marked symbols does not hurt.
This leaves no callers of `HaveExportedObjects`, but leave the
method in place anyway because it may be useful in the future.
Fixes#16161.
Replace use of cmsys::auto_ptr with a CM_AUTO_PTR macro that maps to
our own implementation adopted from the KWSys auto_ptr implementation.
Later we may be able to map CM_AUTO_PTR to std::auto_ptr on compilers
that do not warn about it.
Automate the client site conversions:
git grep -l auto_ptr -- Source/ | grep -v Source/kwsys/ | xargs sed -i \
's|cmsys::auto_ptr|CM_AUTO_PTR|;s|cmsys/auto_ptr.hxx|cm_auto_ptr.hxx|'
In the `try_compile` source file signature we propagate the caller's
value of `CMAKE_<LANG>_FLAGS` into the test project. Extend this to
propagate `CMAKE_<LANG>_FLAGS_<CONFIG>` too instead of always using the
default value in the test project. This will be useful, for example, to
allow the MSVC runtime library to be changed (e.g. `-MDd` => `-MTd`).
However, some projects may currently depend on this not being done,
so we need to activate the behavior using a policy.
This change was originally made by commit v3.6.0-rc1~160^2 (try_compile:
Honor CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11) but without the
policy and so had to be reverted during the 3.6 release candidate cycle.
Fixes#16174.
Clang refuses to default initialize an instance of a class that does not
have a default constructor. Fix the check by adding default
constructors. Don't use brace initialization like it is proposed in the
error message. We want to test the override support independent from
the support for brace initialization.
Revert commit v3.6.0-rc1~160^2 (try_compile: Honor
CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11). The behavior it
introduced can break projects that depend on the lack of such behavior.
We will have to introduce a policy or other mechanism to enable the
behavior in a compatible way. Simply revert it for now.
See issue #16174.
