298# Explanation of some of the targets:
299# - gb_LinkTarget_get_external_headers_target is the targets that guarantees all
300#   headers from linked against libraries are in OUTDIR.
301# - gb_LinkTarget_get_headers_target is the target that guarantees all headers
302#   from the linked against the libraries and the linktargets own headers
303#   (including generated headers) are in the OUTDIR.
304# - gb_LinkTarget_get_target links the objects into a file in WORKDIR.
305# gb_LinkTarget_get_target depends on gb_LinkTarget_get_headers_target which in
306# turn depends gb_LinkTarget_get_external_headers_target.
307# gb_LinkTarget_get_target depends additionally on the objects, which in turn
308# depend build-order only on the gb_LinkTarget_get_headers_target. The build
309# order-only dependency ensures all headers to be there for compiling and
310# dependency generation without causing all objects to be rebuild when one
311# header changes. Only the ones with an explicit dependency in their generated
312# dependency file will be rebuild.
313#
314# gb_LinkTarget_get_target is the target that links the objects into a file in
315# WORKDIR
316# Explanation of some of the variables:
317# - AUXTARGETS are the additionally generated files that need to be cleaned out
318#   on clean.
319# - PCH_CXXFLAGS and PCH_DEFS are the flags that the precompiled headers will
320#   be compiled with.  They should never be overridden in a single object
321#   files.
322# - TARGETTYPE is the type of linktarget as some platforms need very different
323#   command to link different targettypes.
324#
325# Since most variables are set on the linktarget and not on the object, the
326# object learns about these setting via GNU makes scoping of target variables.
327# Therefore it is important that objects are only directly depended on by the
328# linktarget. This for example means that you cannot build a single object
329# alone, because then you would directly depend on the object.
330#
331# A note about flags: because the overriding the global variables with a target
332# local variable of the same name is considered obscure, the target local
333# variables have a T_ prefix.
