Note that AppVeyor has windres.exe in all these locations:
C:\cygwin\bin\windres.exe
C:\cygwin64\bin\windres.exe
C:\MinGW\bin\windres.exe
C:\mingw-w64\i686-5.3.0-posix-dwarf-rt_v4-rev0\mingw32\bin\windres.exe
C:\msys64\mingw32\bin\windres.exe
C:\msys64\mingw64\bin\windres.exe
C:\msys64\usr\bin\windres.exe
C:\Qt\Tools\mingw482_32\bin\windres.exe
C:\Qt\Tools\mingw491_32\bin\windres.exe
C:\Qt\Tools\mingw492_32\bin\windres.exe
C:\Qt\Tools\mingw530_32\bin\windres.exe
C:\Ruby193\DevKit\mingw\bin\windres.exe
C:\Ruby23\DevKit\mingw\bin\windres.exe
C:\Ruby23-x64\DevKit\mingw\bin\windres.exe
