Instead of always adding CMAKE_SHARED_LIBRARY_LINK_<LANG>_FLAGS to
executables, or just when the ENABLE_EXPORTS property is set (CMP0065),
make sure that the target platform also actually supports shared
libraries. If not, then the executable cannot possibly provide symbols
to them anyway.
Classify .manifest sources separately, add dependencies on them, and
pass them to the MS manifest tool to merge with linker-generated
manifest files.

This is needed for proper makefile progress tracking.
The cmLocalGenerator is constructed at configure-time, but only used
at generate time. The StateSnapshot member is currently populated
before configuring, so use the Makefile to get the end snapshot.

Teach the Makefile and Ninja generators to substitute for an <INCLUDES>
placeholder instead of putting -I in <FLAGS>. Update our values for
CMAKE_<LANG>_COMPILE_OBJECT,
CMAKE_<LANG>_CREATE_ASSEMBLY_SOURCE, and
CMAKE_<LANG>_CREATE_PREPROCESSED_SOURCE
to place <INCLUDES> just before <FLAGS>.
The Convert methods never belonged to the local generator concept, so
split them out now. The cmOutputConverter is cheap to construct and
destroy, so it can be instantiated where needed to perform
conversions. This will allow further decoupling of cmLocalGenerator
from the configure step.
Inherit cmLocalGenerator from cmOutputConverter for the purpose of
source compatibility.

The test for this variable was removed in commit v2.8.8~330^2~7 (complex:
Remove ancient unused ComplexRelativePaths test, 2011-12-23).
Commit v3.1.0-rc1~425^2~2 (backtrace: Convert to local paths in
IssueMessage, 2014-03-12) appears to have accidentally made some backtraces
print relative paths with the variable because conversions which used to be
done at configure time, before the variable had an effect are now potentially
done at generate time.
The documentation of the variable says not to use it, and the docs are wrong in
that the variable actually applies in per-directory scope.
The read of the variable makes it harder to split conversion methods from
cmLocalGenerator where they don't belong. Remove it now.
3b880a07 cmLocalGenerator: Require a valid cmState::Snapshot in the ctor.
e12afe76 cmState: Host some state from the cmGlobalGenerator.
c7b79aa1 cmGlobalGenerator: Require a cmake instance in ctor.
01e1cd5c cmState: Move snapshot creation to the cmake instance.
Refactor the local generator creation API to accept a
cmState::Snapshot. Adjust MakeLocalGenerator to use the 'current'
snapshot in cases where there is no parent. Create the snapshot
for subdirectories in cmMakefile::AddSubdirectory.
This means that snapshots are now created at the point of extending the tree,
as appropriate, and independently of the cmLocalGenerator and cmMakefile they
represent the state for.
The <LANG>_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN were first
merged in commit v2.8.12~322 (Merge topic 'VISIBILITY_PRESET-property',
2013-06-05) but worked only for shared libraries and executables with
exports. Prior to commit v3.0.0-rc1~581^2 (GenerateExportHeader:
Deprecate add_compiler_export_flags function., 2013-09-02) the
add_compiler_export_flags function was used to add visibility flags to
all targets.
The visibility flags are useful for sources in all target types because
they may be later linked into shared libraries or executables with
exports. Introduce policy CMP0063 to enable them for all target types
while preserving compatibility with existing projects that do not expect
this.
Don't create a snapshot in Initialize(), but leave the creation
responsibility to the cmake instance instead. Previously, the
cmState would Initialize() in its constructor, and the cmake instance
would re-Initialize() during Configure(). The end result was the
same and there would be one snapshot present. However, cmLocalGenerator
also created a snapshot on construction, and that one was used, leaving
the first snapshot unused, and potential for off-by-one errors.
Fix that by making the cmLocalGenerator use the existing snapshot
if it is top-level. Add a CurrentSnapshot to the cmake instance and
populated it while configuring a directory. This will eventually
replace the 'current local generator' concept. Fix the GetParent
implementation to be able to return the first snapshot.
fa9eb814 cmLocalGenerator: Remove redundant path access.
1933f3d1 cmLocalGenerator: Remove redundant path conversions.
9e4b6cc2 cmState: Store computed relative paths to to current directories.
991f5e49 cmState::Snapshot: Store components for current directories.
57bdc1a2 cmState: Compute and store directory components.
There is no need to duplicate these in all cmLocalGenerators.
Rename the symbols according to current conventions.
Add explicit calls to Set{Source,Binary}Directory with empty strings
in order to trigger the population of the components containers with
the current working directory in cmLocalGenerator. Having
directories set to empty is a special case in CMake, which is relied
on for the `if(CMAKE_BINARY_DIR)` condition at the end of
CMakeDetermineSystem.cmake.
If the CMakeLists.txt file does not exist, there must be a parent.
The case for the top-level of the project is already handled in
cmake::DoPreConfigureChecks.
