Fix unable to compile TiglViewer on gcc (Ubuntu 12.2.0-3ubuntu1) 12.2.0

[Mk-arc]

I checked out the current master and simply tried.

mkdir build
cmake ..
make

which leads to the following error:

/<user>/git/tigl/src/fuselage/ITiGLFuselageDuctStructure.cpp: In function ‘TopoDS_Wire tigl::{anonymous}::project(TopoDS_Shape, BRepProj_Projection&, tigl::DebugScope&)’:
/<user>/git/tigl/src/fuselage/ITiGLFuselageDuctStructure.cpp:111:60: error: variable ‘TopTools_ListIteratorOfListOfShape it’ has initializer but incomplete type
  111 |         for (TopTools_ListIteratorOfListOfShape it(wireList); it.More(); it.Next()) {
      |                                                            ^
/home/kisle/git/tigl/src/fuselage/ITiGLFuselageDuctStructure.cpp:128:60: error: variable ‘TopTools_ListIteratorOfListOfShape it’ has initializer but incomplete type
  128 |         for (TopTools_ListIteratorOfListOfShape it(wireList); it.More(); it.Next()) {

Description

The problem is resolved by importing the proper header required by TopTools_ListIteratorOfListOfShape.

How Has This Been Tested?

running the build again:

mkdir build
cmake ..
make

This time it works.

Checklist:

• A test for the new functionality was added.
• All tests run without failure.
• The new code complies with the TiGL style guide.
• New classes have been added to the Python interface.
• API changes were documented properly in tigl.h.

Thanks! But also strange, since we don't have any problems with gcc in our CI. Which OpenCascade version are you using?

Maybe that's just it. We are currently building TiGL with version 7.4. But either way, adding the missing include makes sense.
