So here is the continuation of that post which is important but
somewhat long because the results for -DUSE_INCRTCL_VERSION_4=ON are
not boringly perfect. That CMake option pulled in version 4 or
Itcl/Itk (also linked against Tcl/Tk8.6) and version 4.1 of Iwidgets.
If I applied the following local build-system patch:

to exclude these two targets from being dependencies of the
test_interactive target, then the test_interactive target ran without
any error message or non-zero return codes. However, there were some
subtle issues with those results that are not present in the version 3
case. The Iwidgets file chooser (which you can get access to by clicking on
"Plot->save->as" for -dev tk) emits an error message that starts as
cannot inherit from "iwidgets::Dialog" (cannot inherit from
"iwidgets::Dialogshell" (cannot inherit from "iwidgets::Shell" (cannot
inherit from "itk::Toplevel" (can't create object "itk::Toplevel":
command already exists with that nameITCL: cannot create
Tcl_NewObjectInstance for class "::itk::Toplevel"))))
....
There is also the same message for part of Plot->Palettes->Palette 0
and Plot->Palettes->Palette 1 if you attempt to "Save Palette" or
"Load Palette". I assume that is because those buttons also
attempt to run the Iwidgets file chooser (which works well
for Version 3 of Itcl and friends).
Note that version 4 of Itcl and friends (i.e., version 4 of Itcl and
Itk and version 4.1.0 of Iwidget) work well otherwise for the colour
palette case; I was able to demonstrate (with the exception of "Save
Palette" and "Load Palette") that all the many different colour
palette sliders and buttons work in detail for both the Palette 0 and
1 cases just like they do for version 3 of Itcl and friends. This good
result is consistent with the extremely small set of differences
between Iwidgets-4.0.1 and Iwidgets-4.1.0 which can be seen in
cmake/build_projects/iwidgets/iwidgets4.1.patch. This small set of
changes allows Iwidgets-4.1.0 to work (with version 4 of Itcl and Itk)
as well as Iwidgets-4.0.1 works (with version 3 of Itcl and Itk). (I
have demonstrated that by trying the Iwidgets calendar and watch demos
in both cases with no issues.) Similarly, I hope only small changes
will be required of our own scripts to get the Iwidgets file chooser
dialog working again. (More below about that.)
The final two tests I made for version 4 of Itcl and friends were to
run the two explicit Itcl tests that I locally removed from the above
"test_interactive" target.
Here are the results for the test_tk_02 target:

So all three error messages are different, but similar. As I
commented about the first (truncated) error message above concerning
the file chooser, I hope from the small changes between Iwidgets 4.1.0
versus 4.0.1 that a small change to our scripts will solve these
issues. Furthermore, a google search for <"cannot inherit from"
"command already exists with that"> found
http://sourceforge.net/p/incrtcl/bugs/182/. I didn't understand that
discussion much (note I don't understand OO concepts tha well) except
that the incrtcl (i.e., version 4 of Itcl and Itk) developers didn't
view the issue as a bug. But if you understand that discussion it may
lead to an easy solution for what changes we have to make to become
completely compatible with Itcl4 and friends.
In sum, when you get to the point (which I assume will be quite some
time from now) of trying out version 4 of Itcl and Itk and version
4.1.0 of Iwidgets, I hope you will be willing to try to fix the above
errors. I am fairly sure those fixes will be straightforward for the
reasons I mentioned, but I am not in a good position to do those fixes
myself because although I know how to fix up the part of the build
system dealing with Tcl and friends and know how to build Tcl8.6 and
friends, I don't really understand the Tcl language (or OO concepts)
that well.
