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