SUMMARY
On the current (05/24/23) snapshot of KDE neon Unstable latte won't build due to cmake errors

'''
CMake Error at CMakeLists.txt:39 (find_package):
  By not providing "FindLibTaskManager.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "LibTaskManager", but CMake did not find one.

  Could not find a package configuration file provided by "LibTaskManager"
  with any of the following names:

    LibTaskManagerConfig.cmake
    libtaskmanager-config.cmake

  Add the installation prefix of "LibTaskManager" to CMAKE_PREFIX_PATH or set
  "LibTaskManager_DIR" to a directory containing one of the above files.  If
  "LibTaskManager" provides a separate development package or SDK, be sure it
  has been installed.

Install plasma-workspace-devel or whatever that package is called on Neon. If this works please let me know and I will send a Merge Request to the INSTALLATION.md file to include it.

this changes the error message:

Just taking a look at the git repository it doesn't look like it's actually been ported to Qt/KF6 yet. I think you'll have to wait for someone to step up and port it. Many apps are still in various stages of being ported.

I'm going to close this bug for now as there's no way to currently build latte dock. Once there is if you face any build issues feel free to open a new bug.
