Man Python

I'm not sure about the sys vars (should be as here https://github.com/kitech/qt.go/issues/43#issuecomment-522253177) and sets CGO_CFLAGS & CGO_LDFLAGS (or do this by set in cmd?). ``` C:\>set CGO_CFLAGS=-ID:/qtenv/include -ID:/qtenv/lib/libffi-3.2.1/include/ C:\>set CGO_LDFLAGS=-LD:/qtenv/lib...

No special changes by this comand ``` C:\>go build -v -x E:\gopath\go\src\github.com\kitech\qt.go\examples\button.go WORK=C:\Users\xxx\AppData\Local\Temp\go-build612429062 github.com/kitech/qt.go/qtrt mkdir -p $WORK\b034\ cd E:\Go\src\github.com\kitech\qt.go\qtrt pkg-config --cflags -- libffi # pkg-config --cflags -- libffi pkg-config: exit...

Now I have error like: ``` Go\src\github.com\kitech\qt.go\qtrt\ffi_invoke.go:10:17: fatal error: ffi.h: No such file or directory compilation terminated. ``` If adding: https://github.com/libffi/libffi/blob/master/include/ffi.h.in ``` Go\src\github.com\kitech\qt.go\qtrt\ffi_invoke.go:10:0: ./ffi.h:52:9: error: macro names must be identifiers...

> I remember this should work. Maybe need use '/' for path seperate. You mind `// #cgo LDFLAGS: -LD:/qtenv_win64/lib/` ? Thats not helping I'm on WinOS, and double \\ not...

@kitech What about the .h files and `ffi_invoke.go` as in post https://github.com/kitech/qt.go/issues/43#issuecomment-522338868 ?

@kitech but is the errors related are unexpected or related with GO or OS like win? Esspecialy the `#ifndef @TARGET@` errors. Do you plan repair something here? Or not coz...
