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.
Enable languages only in the individual test case. Enable the test
everywhere except Visual Studio generators (which do not implement the
properties) and just set fake flags as needed to activate relevant code
paths. Drop unneeded CMAKE_SUPPRESS_REGENERATION which seems to have
been copied from an unrelated test when this test was created.
Drop the VS >= 7 generator's global Configurations member and instead
lookup configurations using cmMakefile::GetConfigurations where needed.
This avoids accumulating all CMAKE_CONFIGURATION_TYPES values ever
encountered by a project() or enable_language() command and allows
the final value to be used in each directory. We don't officially
support per-directory CMAKE_CONFIGURATION_TYPES values but we certainly
should not generate configurations not in the final value in the top
level directory.
This reverts commit f85db2f323.
Discussion by the QtCreator community at
https://bugreports.qt.io/browse/QTCREATORBUG-13695
raises concerns about this particular approach to working with CMake
projects using QtCreator. Also, the functionality and design of the QBS
extra generator was never discussed on the CMake mailing list or with
QtCreator developers. There may be better ways to make the two tools
work together.
In order to avoid committing to long-term support of this generator
prior to such discussion taking place, revert it from CMake for now.
We may restore this or use an alternative design based on results of
such discussion.

The QMacInstallDialog infrastructure no longer works on modern OS X
versions. Drop it and replace the dialog with a simple info box that
explains to the user how to run 'cmake-gui --install' to add symlinks.
Also suggest simply modifying the PATH.
This approach is similar to the Xcode 'xcode-select --install' method
of installing Xcode Command Line Tools.
On OS X add an "--install[=/path/to/bin]" option (defaulting to
/usr/bin) that installs symbolic links into the given directory.
This will help OS X users make the tools available on the command
line even when they sit inside a CMake.app bundle.
Always show the option with its argument separate in summary text.
State in the main documentation that the option and its argument can be
given together too.
In cmMakefile::PushScope, a copy of the closure of keys initialized
in the parent scope is made. In PopScope, essentially the same copy
is inserted back into the parent. That means a lot of duplication
of strings and a lot of string comparisons. None of it is needed,
because the cmDefinitions keys already provide a canonical
representation of what is initialized.
The removal of the separate container also makes the variable handling
code more easy to reason about in general.
Before this patch, configuring llvm uses 200 KiB for the VarInitStack.
Overall peak memory consumption goes from 35.5 MiB to 35.1 MiB.
