Since commit v3.11.0-rc1~467^2 (VS,Xcode: Add CMakeLists.txt sources
without mutating targets, 2017-10-18) we do not add `CMakeLists.txt` to
target sources but instead generate references to them directly. This
accidentally dropped generation of the `.vcxproj.filters` entry for a
source group in which `CMakeLists.txt` is the only member.
Fixes: #18795
Create `CMAKE_VS_SDK_*_DIRECTORIES` variables to tell the VS generator
how to populate fields in `.vcxproj` files that specify SDK directories.
Fixes: #17908
Since commit v3.11.0-rc1~467^2 (VS,Xcode: Add CMakeLists.txt sources
without mutating targets, 2017-10-18) we do not add `CMakeLists.txt` to
target sources but instead generate references to them directly. This
broke projects that explicitly specify their `CMakeLists.txt` file as a
source file because the explicit entry is no longer consolidated with
the generated one.
Teach the relevant generators to avoid duplicating `CMakeLists.txt`
source references and add test cases.
Fixes: #17828
Add a `VS_USER_PROPS_CXX` target property to set the user props file of
the generated `.vcxproj` file to be something other than the default
`$(UserRootDir)\\Microsoft.Cpp.$(Platform).user.props`.
With VS generators for 2010 and above, passing a `.targets` file to
`target_link_libraries` is expected to generate content in the
`.vcxproj` file to import the targets file. Add a test to cover this.
Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.
