Trouble installing samples on win64

[Azecy_]

Hello. I just got the win64 itch binary & am trying to follow the instructions. When trying to install the samples, I get this error:

gcc -c -m32 -msse2 -I"../include" -std=c99 -O2 Barrel.c -o Barrel.o
gcc -c -m32 -msse2 -I"../include" -std=c99 -O2 Simon.c -o Simon.o
gcc Barrel.o Simon.o -o barrel ../lib/win32/Tilengine.lib -s
gcc: error: ../lib/win32/Tilengine.lib: No such file or directory
mingw32-make: *** [Makefile:42: barrel] Error 1

Please let me know what I need to do next. Thank you.
