KDevelop crashes when importing cmake-based C++ project

Fri May 15 20:04:02 BST 2020

I have posted this message on the KDE Bug Tracking System, and on StackOverflow, without success.

Basically, I have a simple cmake-based C++ project (of about 25 source and header files) which compiles and runs without problems ("cd build && cmake ../src && make && sudo make install"). The project has a 'src' directory which holds the topmost CMakeLists.txt file. When I run KDevelop, and choose "Open/Import Project", and then choose that CMakeLists.txt file, KDevelop starts importing the project, but crashes before the progress bar at the right bottom reaches 98%. The KDevelop output is below; I can't make sense of it. I should note that I can import that same project into 'Qt Creator' and other IDEs/SDEs without problems.

Using KDevelop 5.5.1 on Fedora 31 with KDE/Plasma and gcc/g++ 9.2.1.
