# FreeType build system -- top-level sub-Makefile |

# This file is designed for GNU Make, do not use it with another Make tool! |
|
# |
|
# It works as follows: |
|
# |
|
# - When invoked for the first time, this Makefile includes the rules found |
|
# in `PROJECT/builds/detect.mk'. They are in charge of detecting the |
|
# current platform. |
|
# |
|
# A summary of the detection is displayed, and the file `config.mk' is |
|
# created in the current directory. |
|
# |
|
# - When invoked later, this Makefile includes the rules found in |
|
# `config.mk'. This sub-Makefile defines some system-specific variables |
|
# (like compiler, compilation flags, object suffix, etc.), then includes |
|
# the rules found in `PROJECT/builds/PROJECT.mk', used to build the |
|
# library. |
|
# |
|
# See the comments in `builds/detect.mk' and `builds/PROJECT.mk' for more |
|
# details on host platform detection and library builds. |
|
|
|
|
|
# First of all, check whether we have `$(value ...)'. We do this by testing |
|
# for `$(eval ...)' which has been introduced in the same GNU make version. |
|
