# UPX top-level Makefile - needs GNU make and CMake >= 3.13
# Copyright (C) Markus Franz Xaver Johannes Oberhumer

# INFO: this Makefile is just a convenience wrapper for calling CMake

# HINT: if you only have an older CMake 3.x then you can invoke cmake manually like this:
#   mkdir -p build/release
#   cd build/release
#   cmake ../..         # run config
#   make -j4            # and run build

CMAKE = cmake
UPX_CMAKE_BUILD_FLAGS += --parallel
ifneq ($(VERBOSE),)
  #UPX_CMAKE_BUILD_FLAGS += --verbose # requires CMake >= 3.14
  UPX_CMAKE_CONFIG_FLAGS += -DCMAKE_VERBOSE_MAKEFILE=ON
endif
# enable this if you prefer Ninja for the actual builds:
#UPX_CMAKE_CONFIG_FLAGS += -G Ninja
