Temporarily restore previous behavior that allowed specifying
no source or build directory to work, even though it was
neither documented nor supported. This commit is expected
to eventually be reverted to restore the fatal error for such
cases.

If only the source dir is provided, the binary dir is assumed
to be the working directory. If only the binary dir is provided
and it doesn't yet have a CMakeCache.txt to provide the
source dir, then the source dir is assumed to be the working
directory. This logic was not previously being handled
correctly when -S and/or -B options were involved.
Furthermore, when both were missing, no suitable error
message was provided and an empty string was used for
the build directory.

Fixes: #18707

While an error message was being logged, processing was
continuing nonetheless except with the -P argument omitted.
This could have allowed unintended effects if the remaining
arguments formed a valid set of command line options.

We used to silently disable AUTOMOC/UIC/RCC when no valid Qt
version was found.  This patch introduces the generation of
a warning message in that case.

Closes #18732.

This results in the correct source directory being picked up in calls
with

    cmake sourcedir -C settings

and in a more appropriate error message when calling

    mkdir build ; cd build ; cmake -C settings

Also fix `-D` and `-U` in the same way.

Commit v3.13.0-rc1~279^2 (GetPrerequisites: Move dylibs from MacOS
to Frameworks folder in bundle, 2018-07-22) introduced a regression
that can cause symlink creation to fail during packaging. Symlinks
can be created before targets are installed, so the destination
directory of the symlink sometimes won't exist at symlink creation.

Passing an incomplete list of compiler include directories causes
a regression in the KIO project (and probably others). We need to
disable it until the complete list is available (see #16291).

In CMake 3.13.0 when a target has ``AUTOUIC`` enabled but doesn't
link against Qt5Widgets, the uic executable string is empty and
an error string "The uic executable \"\" does not exist" is generated.
In CMake 3.12 ``AUTOUIC`` was silently disabled instead.
This patch fixes the regression and restores the behavior of CMake 3.12.

Move the filter added by commit v3.13.0-rc1~72^2~2 (VS: Do not select a
Windows SDK too high for current VS version, 2017-08-07, committed
2018-09-17) to before our check that the remaining list is empty.
Otherwise we crash when dereferencing the first entry of an empty
vector.

Also add a comment explaining where 10.0.14393.0 came from.

Since commit v3.13.0~7^2 (FindBoost: Improve compiler prefix
detection for GCC 5+ and clang 4+, 2018-11-07) we run the internal
`_Boost_COMPILER_DUMPVERSION` macro on all UNIX platforms.  Teach
the macro to tolerate missing `CMAKE_CXX_COMPILER_VERSION`, which
occurs when the CXX language is not enabled.
