Error: undefined reference to `__imp_TaskDialog'

Just tried running the the example code and got this error:

C:\Users\dev\go\src\github.com\brunocassol\gopic>go run main.go
# github.com/andlabs/ui
C:/Users/dev/go/src/github.com/andlabs/ui/libui_windows_amd64.a(stddialogs.cpp.obj): In function `msgbox':
E:/github.com/andlabs/libui/windows/stddialogs.cpp:113: undefined reference to `__imp_TaskDialog'
collect2.exe: error: ld returned 1 exit status
