# This sub-Makefile is in charge of detecting the current platform. It sets
|
||
# the following variables:
|
||
#
|
||
# BUILD_DIR 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.
|
||
# COMPILER_SEP The separator used in arguments of the compilation tools.
|
||
# CC The compiler to use.
|
||
#
|
||
# You need to set the following variable(s) before calling it:
|
||
#
|
||
# TOP_DIR The top-most directory in the FreeType library source
|
||
# hierarchy. If not defined, it will default to `.'.
|
||
|
||
# Set auto-detection default to `ansi' resp. UNIX-like operating systems.
