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 `.'. # If TOP_DIR is not defined, default it to `.' # ifndef TOP_DIR TOP_DIR := . endif # Set auto-detection default to `ansi' resp.
