# PRIVACY - dependency can be inherited by dependent targets or not:
# PUBLIC - this should be used by default, cause compile/link flags passing
# PRIVATE - do not passes any settings to dependent targets,
# may be usefull for static libraries from the inside of the project
# Argument ARGV2 and following are supposed to be names of checked pkg config
