Dear Stefan,
I ran into the same problem as Nil did concerning the Qt5::WebEngine not found
error.
I've build version 2021.02 of mitk using the superbuild option and then
deployed a ProjectTemple using the PuginGenerator.
The Qt5::WebEngine error arises, when compiling the deployed ProjectTemplate.
And it's the only error I get.
The CmakeLists.txt in the "Apps" folder calls the cmake function
"mitkFunctionCreateBlueBerryApplication", where it adds MODULE MitkAppUtil to
the application. (Btw: The line "mitk_use_modules(TARGET ${MY_APP_NAME} MODULES
MitkAppUtil)" is redundant here because the module is already being added
inside "mitkFunctionCreateBlueBerryApplication.cmake#103".)
The problem seems to be that the module AppUtil sets its qt dependencies as
follows "set(qt5_depends Qt5|Widgets+WebEngine)".
You told Nil that the module "infects" the build with this dependency and qt
does not find the WebEngine lib automatically during superbuild. At least not
for me and I don't know why that is. It also does not work for me to manually
declare the Qt5_WebEngine path in cmake. Initially I did not have WebEngine
downloaded in my qt dir so I had to modify my qt setup after the superbuild was
already completed once. Maybe that's one potential problem?
Anyway, I had a closer look at the AppUtil module. This module seems to use
only the includes header "<QWebEngineUrlScheme>", which is part of
"Qt5WebEngineCore". Since there are no other decencies to WebEngine functions
at this level I figure that it's not necessary to depend on the entire
WebEngine module here.
So, changing line 1 in :
\\MITK2021\src\Modules\AppUtil\CmakeLists.txt<file://MITK2021/src/Modules/AppUtil/CmakeLists.txt>
from
set(qt5_depends Qt5|Widgets+WebEngine)
to only
set(qt5_depends Qt5|Widgets+WebEngineCore)
seems to fix the issue for me.

Hi,
my first guess is that your executable is infected with this dependency from
MitkAppUtil, which has a PUBLIC package dependency to WebEngine. Usually CMake
is right in its assumptions regarding find_package(). So a first step would be
to do a manual find_package for WebEngine and continue from there. If it still
cannot be found, but other components of Qt were found, double-check your
installation and maybe manually look for the Config.cmake file in the lib/cmake
subfolder of your Qt installation. Since you seem to use MITK as library it is
hard to make better guesses at the moment. I also did not use Qt 5.15 yet, only
5.12.
Best,
Stefan

Hi Stefan,
My module wasn't found because I included "MitkTestingHelper" in the wrong
place. There was no useful error message so I had to guess it.
But now I have another problem and you may be able to help me. The CMake
Configure part is ok, but when I click on Generate, I get this error
CMake Error at
C:/Imeka/mitk/CMake/mitkFunctionCreateBlueBerryApplication.cmake:88
(add_executable):
Target "MI-Brain" links to target "Qt5::WebEngine" but the target was not
found. Perhaps a find_package() call is missing for an IMPORTED target, or
an ALIAS target is missing?
Call Stack (most recent call first):
Apps/MI-Brain/CMakeLists.txt:34 (mitkFunctionCreateBlueBerryApplication)
which is surprising because I don't use or try to include WebEngine. A git grep
WebEngine returns nothing. And I know and verified that I installed WebEngine
along with Qt 5.15.X. Do you know what is causing this?

Hi Nil,
you do *not* need to use the ProjectTemplate but it is at least the strongly
recommended way for new MITK developers to go the framework route with MITK.
You can still continue using MITK as plain CMake-based toolkit/library. As
written in T27701, we just want to get rid of the ProjectGeneration part, not
the PluginGeneration part.
We focus on the ProjectTemplate since we recognized that most of the external
developers are not primarily developers but scientists and while they usually
have at least a basic level of knowledge in C++ to get things done, CMake is
already something different. Using the ProjectTemplate basically means using
MITK as we do internally (which is a big plus for us regarding support) and
that people just need to add modules, plugins, or dependencies to an existing
application backed by examples/templates.
When a module is suddenly missing it is probably related to a missing implicit
dependency that is not there anymore (we revisited the ITK dependencies of all
MITK modules in v2021.02 for example). The CMake output / summary should print
out why a module is missing.
Best,
Stefan

Betreff: [mitk-users] PluginGenerator and ProjectTemplate
Hi all,
I tried porting my application to 2121.02 and there's plenty of cmake errors
because one of my modules is suddenly missing. So I tried using the good old
PluginGenerator, but I see that there's a problem with it. It's not built when
I build MITK. It was decided in T27701<https://phabricator.mitk.org/T27701> to
get rid of it. I learned that there's a
ProjectTemplate<https://phabricator.mitk.org/source/mitk-projecttemplate/>. Is
the old method (our project linking to MITK_BUILD) not working anymore? Can you
please confirm that we must now use this ProjectTemplate?
