The errors "no project() command is present" and "unknown cmake command gnc_add_swig_guile_command" are from telling cmake to start with gnucash-4.11/gnucash/CMakeLists.txt instead of gnucash-4.11/CMakeLists.txt, that is `cmake $SRCROOT/gnucash` instead of `cmake $SRCROOT`.

You must have run cmake inside of the source directory at some point, otherwise there would be no "/home/kt/Sources/gnucash-4.11/CMakeFiles/CMakeOutput.log". The existence of a CMakeCache.txt in $SRCROOT overrides the CMakeLists.txt there and foils any future build attempts.

Do the following:
  cd /home/kt/Sources
  rm -rf gnucash-4.11
  tar -xf /home/kt/Downloads/gnucash-4.11.tar.bz2 # Substitute the path you downloaded if it's different
  cd /home/kt/gnucash-build # Or wherever gnucash-build is really
  cmake /home/kt/Sources/gnucash-4.11

to make sure everything is clean.

You said in your first message that you'd had to install several packages and create /glib-2.0, but you didn't say how you'd done that. If you used dnf and installed the development packages then that's OK, but having to create /glib-2.0 (you meant /usr/lib64/glib-2.0, right?) indicates that you'll need to install a bunch of developer packages for at least the gtk stack. Cmake will continue to fail until you've satisfied all of the dependencies with headers as well as libraries; headers come from the development version of packages, commonly named with a -dev or -devel suffix, e.g. `sudo dnf install glib2-devel`.
