[Rtk-users] problem with cmake

[Andreas Andersen]

It should not be necessary to set `Gengetopt_DIR`

I think what you actually need is to have a `find_package(ITK REQUIRED)`
before your `find_package(Gengetopt REQUIRED)` (and you'll need ITK for RTK
anyway)

Reading "FindGengetopt.cmake" from ITK, I can see it defines the `WRAP_GGO`
macro. So we just want to trigger this Find script.
(I'm unsure if it's also necessary to have `include(${ITK_USE_FILE})`
before `find_package(Gengetopt REQUIRED)`, but it might be)

So I would recommend something like:
```
cmake_minimum_required(VERSION 3.9.5 FATAL_ERROR)

project(rtkprojectgeometricphantom)

find_package(ITK REQUIRED)
include(${ITK_USE_FILE})

find_package(Gengetopt REQUIRED)
```
