Hi all, could I have some feedback on my github pull request ?

Hi all,
I would like to do the final step: put the content of the new vtkSlicerVersionConfigure.h into a resource file which is read at runtime in /home/aymeric/dev/slicer/Base/QTCore/qSlicerCoreApplication.cxx.
Did you already plan to do it ?
Do you have any idea/advice to implement it correctly ?
Best regards

Since the current use of the macro is for conditionally including code at compile time, i am not this approach would work here.
That said, i suggest we list the current use of the macros to make the final call.

I have not found code which uses the constant of vtkSlicerVersionConfigure.h (not vtkSlicerVersionConfigureMinimal.h) in #if or #ifdef statements.
Am I wrong ?

Inspecting the source files, we can see the following files directly including `vtkSlicerVersionConfigure.h`:
```auto
$ pwd
/path/to/Slicer
```
```auto
$ ack --cpp vtkSlicerVersionConfigure\.h
Base/Logic/Testing/vtkSlicerVersionConfigureTest1.cxx
21:#include "vtkSlicerVersionConfigure.h"
Base/QTGUI/qSlicerApplication.cxx
41:#include // For Slicer_VERSION_FULL
Base/QTApp/qSlicerApplicationHelper.cxx
43:#include "vtkSlicerVersionConfigure.h" // For Slicer_MAIN_PROJECT_VERSION_FULL
Base/QTCore/Testing/Cxx/qSlicerUtilsTest1.cxx
36:#include "vtkSlicerVersionConfigure.h"
Base/QTCore/qSlicerCoreApplication.cxx
138:#include "vtkSlicerVersionConfigure.h"
Applications/SlicerApp/Main.cxx
25:#include "vtkSlicerVersionConfigure.h" // For Slicer_VERSION_FULL
```
… then reading the comments in the respective `.cxx` files you will be able to assess which macro are used.

After modifying `vtkSlicerVersionConfigure.h`, the following executable and libraries are rebuilt:
```auto
bin/SlicerBaseLogicCxxTests
bin/libqSlicerBaseQTCore.so
bin/qSlicerBaseQTCoreCxxTests
libqSlicerBaseQTGUI.so
libqSlicerBaseQTApp.so
SlicerApp-real
```
Details output:
```auto
$ touch vtkSlicerVersionConfigure.h
$ make
