# Plugins can implement a acg_list_filter ("listname") macro to filter out
# unneeded headers, sources and ui files from the autogenerated
# build sources lists (see common.cmake drop_templates macro)
#
# Translations
# Create a subdirectory called translations in your Plugin directory
# The *.ts files there will be used for the translations
#
# Special DEPS:
# CUDA:
# If your plugin requires cuda, add "CUDA" to the list of dependencies
# and create a subdir called Cuda in your plugin directory
# The files in this directory will be compiled by nvcc and linked
# into the plugin
#
# The variables PLUGIN_${plugin}_MISSING_DEPS indicate whether any mandatory
# dependencies of the respective plugins are missing.
