# Makefile for building curl parts with MinGW and optional features.
#
# Usage:   mingw32-make -f Makefile.m32 CFG=-feature1[-feature2][-feature3][...]
# Example: mingw32-make -f Makefile.m32 CFG=-zlib-ssl-sspi-winidn
#
# Set component roots via envvar <feature>_PATH. Also available for
# customization: CC, RC, AR, CPPFLAGS, LDFLAGS, LIBS, CFLAGS, RCFLAGS,
# ARCH[=custom], CROSSPREFIX, CURL_LDFLAGS_BIN, CURL_LDFLAGS_LIB, CURL_DLL_SUFFIX,
# and more for individual components (see below).

# This script is reused by 'src' and 'docs/examples' Makefile.m32 scripts.
# Skip lib-specific parts when called through them.
