libreCMC/scripts/config/Makefile

# ===========================================================================
# libreCMC configuration targets
# These targets are used from top-level makefile

# ===========================================================================
# Shared Makefile for the various kconfig executables:
# conf:	  Used for defconfig, oldconfig and related targets
# mconf:  Used for the mconfig target.
#         Utilizes the lxdialog package
# qconf:  Used for the xconfig target
#         Based on Qt which needs to be installed to compile it
# object files used by all kconfig flavours


# Platform specific fixes
#
# FreeBSD
