The default setting for "Full Path of Source Code File in Diagnostics"
changed with VS 2017: it's now turned on by default. It can also be
enabled with the compiler flag /FC, but there is no flag for turning it
off.
Users might want to disable /FC to obtain reproducable binaries.
Change qmake's default from "use Visual Studio's default" to "off" for
this feature. Users can enable it manually by putting the following
into their project files:
QMAKE_CXXFLAGS += /FC
CMake faced the same problem. See CMake upstream issue #18261 for
comparison.
Pick-to: 5.15 6.2 6.3 6.4
