+# *******************************************
+# Use gb_DEBUG_STATIC=t to dump various debug info for the static build preparation!
+# Use gb_DEBUG_STATIC=a to abort / error after the dump
+# *******************************************
+#
+# "Generic" comment from the author:
+# My thought was: the dependency info is already there. Can't be too hard to use it for
+# correct static linkage... well it took more than two weeks to hopefully identify all
+# problems / edge cases. Now I can appreciate the usage bin/lo-all-static-libs even more.
+#
+# This code moved a few times to the various gbuild / make phases: Makefile / module
+# setup (in use_(libraries|externals)), post parsing (like now), make "dependency" tree
+# processing. It currently looks like this is the only working option.
+#
+# For static linking, we must collect all depending libraries, externals and statics to
+# be available at link time. And Libraries and externals can use each other. This could
+# be done "in-line", while make processes the dependency tree and would have the correct
+# order, so no separate tree-walking would be needed.
+# It can't be done while reading / processing the modules, as this happens in no order, so
+# depending modules will be missing.
+#
+# Then there is the (gbuild new) concept of plugin libraries. These depend on some loader
+# libraries, like vcl and vclplug_* or gie. For a shared library build, these plugins are
+# just dlopen'ed, but for a static build, any linked binary must also link the plugins, which
+# turns plugins + loaders into a dependency cycle. The implemented solution is to just add
+# plugins to executables, if these depend on a loader library. This results in the additional
+# rule: nothing non-plugin is allowed to depend on a plugins (see gb_Library_set_plugin_for).
+#
+# And we can't add these dependencies while make is already processing the Executables,
+# because these contain additional eval'ed targets, which we can't create in make recipes.
+# This is especially true for externals (see gb_LinkTarget__use_* in RepositoryExternal.mk).
+# We also can't add all plugins to all executables, as we have multiple helper
+# binaries, which are needed early and don't depend on plugins.
+#
+# So the only option left seems to be to walk the dependency tree ourself and expand all
+# the libraries and externals and then add the plugins to the executables. Statics are
+# handled after that, since these won't need extra dependencies not already known.
+# It's a bit fragile in theory, as you can add "gbuild-undetectable" dependencies to any
+# target in the modules, which would need some manual adjustment, but currently that
+# doesn't seem to happen in any breaking way and it works to link multiple Executable
+# with large and small expanded dependency lists.
+#
+# Then there is the special static "components" library, which simply depends on all build
+# components. In theory these could be limited per-module (Writer, Calc, etc.), but currently
+# this is not implemented and instead solenv/bin/native-code.py is used, so actually
+# everything is build and "cleaned up" at link time, which is especially expensive for WASM.
+# That library is currently just used for Emscripten, but could be used generally for
+# static builds.
+#
+# There is already a lot of $(info ...) protected by the already mentioned $(gb_DEBUG_STATIC).
