# TODO
# Vckpg:
# - Improve install code once there is better way to deploy DLLs and Qt plugins
#
# Other:
# - Cleanup remove_directory copy_directory if performance will be a problem.
# We can use some macro over copy_if_different since it's only work for single file.
# - Find a way to move add_custom_command for assets deploy out of "lib/CMakeLists.txt"
# - Consider to remove M_DATA_DIR, DM_BIN_DIR, DM_LIB_DIR and not use them in code as well
# - Try to get rid of FOLDER override with define_property
# It's used currently to make sure that 3rd-party dependencies in git submodules get proper FOLDER property
# - Make FindFuzzyLite check for the right version and disable FORCE_BUNDLED_FL by default
