| # 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. |
