The bug was introduced in 352ba2d69a
"Windows: Fix building of resource files when config.h isn't used."
That commit fixed liblzma.dll build with CMake while keeping it
working with Autotools on Windows but the VS project files were
forgotten.
I haven't tested these changes.
Thanks to Olivier B. for reporting the bug and for the initial patch.
I understood that if a WTPV is specified, it's often wrong
because different VS installations have different SDK version
installed. Omitting the WTPV tag makes VS2017 default to
Windows SDK 8.1 which often is also missing, so in any case
people may need to specify the WTPV before building. But some
day in the future a missing WTPV tag will start to default to
the latest installed SDK which sounds reasonable:
