# match the target name, we are depending on a linktarget that was never
# declared. In a full build exclusively in gbuild that should never happen.
# However, partial gbuild build will not know about how to build lower level
# linktargets, just as gbuild can not know about linktargets generated in the
# old build.pl/dmake system. Once all is migrated, gbuild should error out
# when is is told to depend on a linktarget it does not know about and not

# Explanation of some of the targets:
# - gb_LinkTarget_get_external_headers_target is the targets that guarantees all
#   headers from linked against libraries are in OUTDIR.
# - gb_LinkTarget_get_headers_target is the target that guarantees all headers
#   from the linked against the libraries and the linktargets own headers
#   (including generated headers) are in the OUTDIR.
# - gb_LinkTarget_get_target links the objects into a file in WORKDIR.
# gb_LinkTarget_get_target depends on gb_LinkTarget_get_headers_target which in
# turn depends gb_LinkTarget_get_external_headers_target.
# gb_LinkTarget_get_target depends additionally on the objects, which in turn
# depend build-order only on the gb_LinkTarget_get_headers_target. The build
# order-only dependency ensures all headers to be there for compiling and
# dependency generation without causing all objects to be rebuild when one
# header changes. Only the ones with an explicit dependency in their generated
# dependency file will be rebuild.
#
# gb_LinkTarget_get_target is the target that links the objects into a file in
# WORKDIR
# Explanation of some of the variables:
# - AUXTARGETS are the additionally generated files that need to be cleaned out
#   on clean.
# - PCH_CXXFLAGS and PCH_DEFS are the flags that the precompiled headers will
#   be compiled with.  They should never be overridden in a single object
#   files.
# - TARGETTYPE is the type of linktarget as some platforms need very different
#   command to link different targettypes.
#
# Since most variables are set on the linktarget and not on the object, the
# object learns about these setting via GNU makes scoping of target variables.
# Therefore it is important that objects are only directly depended on by the
# linktarget. This for example means that you cannot build a single object
# alone, because then you would directly depend on the object.
