# 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/builds/$(PLATFORM)' but can be different for
# custom builds of the library.
#
# 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 configuration sub-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' resp. UNIX-like operating systems.
# Note that we delay evaluation of $(BUILD_CONFIG_), $(BUILD), and
# $(CONFIG_RULES).
#
PLATFORM := ansi
DELETE := $(RM)
COPY := cp
SEP := /
BUILD_CONFIG_ = $(TOP)$(SEP)builds$(SEP)
BUILD = $(BUILD_CONFIG_)$(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 `builds/<system>'
# directories. Note that the calling order of the various `detect.mk' files
# isn't predictable.
#

# In case no detection rule file was successful, use the default.
