| 17 | # |
| 18 | # It works as follows: |
| 19 | # |
| 20 | # - When invoked for the first time, this Makefile will include the rules |
| 21 | # found in `freetype/config/detect.mk'. They are in charge of detecting |
| 22 | # the current platform. |
| 23 | # |
| 24 | # A summary of the detection will be displayed, and the file `config.mk' |
| 25 | # will be created in the current directory. |
| 26 | # |
| 27 | # - When invoked later, this Makefile will include the rules found in |
| 28 | # `config.mk'. This sub-Makefile will define some system-specific |
| 29 | # variables (like compiler, compilation flags, object suffix, etc.), then |
| 30 | # include the rules found in `freetype/config/freetype.mk', used to build |
| 31 | # the library. |
| 32 | # |
| 33 | # See the comments in `config/detect.mk' and `config/freetype.mk' for more |
| 34 | # details on host platform detection and library builds. |
