Warning: #define main ModuleEntryPoint (-fvar-tracking-assignments)

[phcerdan]

Where on the platform does it happen?

Tested on linux (archlinux with latest stable packages: gcc8.2.1, cmake 3.13.4, etc).

How do we replicate the issue?

Compiling Slicer branch integrating itk5 (points to current master 2af1e31a8ead1471ae33656cf6b02dbb27feb217 )

Expected behavior (i.e. solution)

No warnings
