The "documentation" for writing Makefiles boils down to: try to find
something similar in the main GRASS tree and use its Makefile as a
reference; if there isn't one, or if that doesn't work, ask on the
developers' list.
Writing documentation for this will result in either wasted effort
(from describing situations which never actually happen) or inadequate
documentation (from failing to describe situations which actually
happen) or (most likely) both.
A couple of points about wx.metadata specifically:
1. Using "parsubdirs" won't work as, because mdlib (presumably) needs
to be built before any of the modules.
2. Files should not be installed using "cp"; use $(INSTALL) for
anything which should be installed with execute permission or
$(INSTALL_DATA) for anything without it.
3. Directories shouldn't be copied with "cp -r". Rather, the
individual destination files should be listed as pre-requisites, so
that "building" the target "builds" the destination files (typically
via pattern rules).
wx.metadata/Makefile should probably include "templates" and "config"
in $(SUBDIRS). These would have their own Makefiles; e.g. for
templates/Makefile, something like:
        include $(MODULE_TOPDIR)/include/Make/Other.make
 
        DSTDIR = $(ETC)/mdlib/templates
 
        SRCFILES := $(wildcard *.xml)
        DSTFILES := $(patsubst %.xml,$(DSTDIR)/%.xml,$(SRCFILES))
 
        default: $(DSTFILES)
 
        $(DSTDIR)/%.xml: %.xml:
                $(INSTALL_DATA) $< $@
This should allow wx.metadata/Makefile to be a simple "directory"
Makefile (i.e. set SUBDIRS, include Dir.make, "default: subdirs").

-bbb Force blank lines before block comments.
-bli1 Indent braces 1 space.
-bls Put braces on the line after struct declaration lines.
-br Put braces on line with if, etc.
-cbi0 Indent braces after a case label 0 spaces.
-ci4 Continuation indent of 4 spaces.
-cli0 Case label indent of 0 spaces.
-d0 Set indentation of comments not to the right of code to 0 spaces.
-di0 Put variables in column 0.
-fc1 Format comments in the first column.
-hnl Prefer to break long lines at the position of newlines in the input.
-i4 Set indentation level to 4 spaces.
-ip4 Indent parameter types in old-style function definitions by 4 spaces.

-lc80 Set maximum line length for comment formatting to 80.
-lp Line up continued lines at parentheses.
-nbad Do not force blank lines after declarations.
-nbbo Do not prefer to break long lines before boolean operators.
-nbc Do not force newlines after commas in declarations.
-ncdb Do not put comment delimiters on blank lines.
-nce Do not cuddle } and else.
-ncs Do not put a space after cast operators.
-nfca Do not format any comments.
-npcs Do not put space after the function in function calls.
-nprs Do not put a space after every '(' and before every ')'.
-npsl Put the type of a procedure on the same line as its name.
-nsob Do not swallow optional blank lines.
-pi4 Specify the extra indentation per open parentheses '(' when a statement is broken.
-sbi0 Indent braces of a struct, union or enum 0 spaces.
-sc Put the `*' character at the left of comments.
-ss On one-line for and while statments, force a blank before the semicolon.
-ts8 Set tab size to 8 spaces.
GRASS Makefile writing

PGM must be set before including Module.make.

In general, the point at which variables get defined doesn't matter if they are only used in commands, but it matters if they are used in the dependency line. Essentially, dependency lines get expanded at the point they are read, while commands are expanded at the point they are executed.

The list of variables where the order is significant is:

       PGM
       LIB_NAME
       SUBDIRS
       CMD_OBJS
       LIB_OBJS
       LOCAL_HEADERS
       EXTRA_HEADERS
       DEPENDENCIES


The "documentation" for writing Makefiles boils down to: try to find something similar in the main GRASS tree and use its Makefile as a reference; if there isn't one, or if that doesn't work, ask on the developers' list.

Writing documentation for this will result in either wasted effort (from describing situations which never actually happen) or inadequate documentation (from failing to describe situations which actually happen) or (most likely) both.

1. Using "parsubdirs" won't work as, because mdlib (presumably) needs to be built before any of the modules.

       SRCFILES := $(wildcard *.xml)
       DSTFILES := $(patsubst %.xml,$(DSTDIR)/%.xml,$(SRCFILES))
 
       default: $(DSTFILES)
 
       $(DSTDIR)/%.xml: %.xml:
               $(INSTALL_DATA) $< $@

This should allow wx.metadata/Makefile to be a simple "directory" Makefile (i.e. set SUBDIRS, include Dir.make, "default: subdirs").
