vendor/mediatek/proprietary/hardware/mtkcam/mtkcam.mk
定义所属模块路径属性

MTK_MTKCAM_PLATFORM := $(MTK_PATH_SOURCE)/hardware/mtkcam/legacy/platform/$(PLATFORM)

定义log等级

ifeq ($(TARGET_BUILD_VARIANT), user)
    MTKCAM_LOG_LEVEL_DEFAULT   := 2
else ifeq ($(TARGET_BUILD_VARIANT), userdebug)
    MTKCAM_LOG_LEVEL_DEFAULT   := 3
else
    MTKCAM_LOG_LEVEL_DEFAULT   := 4
endif
