# Support doxygen cross references from each library to each other library:
# First generate the docs to make sure all .tag files are in place.
# In a second run, generate the content with proper referencing.
# For example, libosmocore references tags from libosmovty and vice versa,
# so both need to generate tag files first, and then do another run.
#
# Generate each docs tree, and touch a libosmofoo.tag.prep file when done.
# It means that a libosmofoo.tag file is up-to-date.
# Touch a separate "*.prep" target: libosmofoo.tag as target would create
# circular dependency: we would rebuild all every time 'make' is invoked.
# The .prep file also depends on all the source files for that library.

# Build for real once all depending .tag files are in place.

# tree, and to also depend on all the source files listed above.
#
# Each library should depend on all the tag.prep files of which it lists .tag
# files in Doxyfile under TAGFILES.
#
# In turn, include all .tag files in TAGFILES of libraries to which "\ref"
# references point.
#
# Easiest is to just depend on all tag.prep files all across everywhere.
