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