freetype/config/detect.mk
Werner Lemberg febe3fbeba A first check of FT2's Make system. Many smaller and larger bugs have been
fixed:

. Removing unused variables.

. detect.mk files now must provide $(CONFIG_FILE) and not $(CONFIG_RULE).

. ansi.mk will now be really used as a fallback if the detect mechanism
  fails.

. ANSIFLAGS will now be really used (fixing a typo).

. `make clean' now works (again two typos).

. Detection of gcc on Unix has been fixed (using the `-v' option instead of
  `--version').

. `make devel' now works (on Unix).

. Fixing *again* a bug in demos/graph/x11/rules.mk to allow multiple use
  of `-L' compiler options.

. $(BASE_H) now contains a few more header files.

As usual, a lot of formatting (not finished yet).

# This sub-Makefile is in charge of detecting the current platform. It sets
# the following variables:
#
# BUILD The configuration and system-specific directory. Usually
# `freetype/config/$(PLATFORM)' but can be different if a
# specific compiler has been requested on the command line.
#
# The following variables must be defined in system specific `detect.mk'
# files:
#
# PLATFORM The detected platform. This will default to `ansi' if
# auto-detection fails.
# CONFIG_FILE The Makefile to use. This usually depends on the compiler
# defined in the `CC' environment variable.
# DELETE The shell command used to remove a given file.
# COPY The shell command used to copy one file.
# SEP The platform-specific directory separator.
# CC The compiler to use.
#
# You need to set the following variable(s) before calling it:
#
# TOP The top-most directory in the FreeType library source
# hierarchy. If not defined, it will default to `.'.
# If TOP is not defined, default it to `.'
#
ifndef TOP
TOP := .
endif
# Set auto-detection default to `ansi'.
# Note that we delay the evaluation of $(CONFIG_), $(BUILD), and
# $(CONFIG_RULES).
#
PLATFORM := ansi
DELETE := $(RM)
COPY := cp
SEP := /
CONFIG_ = $(TOP)$(SEP)config$(SEP)
BUILD = $(CONFIG_)$(PLATFORM)
CONFIG_RULES = $(BUILD)$(SEP)$(CONFIG_FILE)
# We define the BACKSLASH variable to hold a single back-slash character.
# This is needed because a line like
#
# SEP := \
#
# does not work with GNU Make (the backslash is interpreted as a line
# continuation). While a line like
#
# SEP := \\
#
# really defines $(SEP) as `\' on Unix, and `\\' on Dos and Windows!
#
BACKSLASH := $(strip \ )
# Now, include all detection rule files found in the `config/<system>'
# directories. Note that the calling order of the various `detect.mk' files
# isn't predictable.
#
include $(wildcard $(CONFIG_)*/detect.mk)
# In case no detection rule file was successful, use the default.
