Could not find a package configuration file provided by "libpanda-files"

[probonopd]

Cannot compile:

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

    libpanda-filesConfig.cmake
    libpanda-files-config.cmake

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

-- Configuring incomplete, errors occurred!
See also "/tmp/panda-qt5-plugin/build/CMakeFiles/CMakeOutput.log".

Please advise. Thank you.

Not sure whether this breaks critical functionality. But at least I can compile.

When I run an application with QT_QPA_PLATFORMTHEME=panda vlc, then the menu does show up. Good! :+1:

Removing panda-files dependencies did not destroy key functions, It provides a unified open file dialog box for all qt applications here :+1:
