如何使CMake使用现有的Makefile? [英] How to get CMake to use existing Makefile?

问题描述

我有一个现有的项目(wvdial)，该项目具有有效的Makefile.我正在尝试将其集成到使用CMake的主要构建过程中.有人可以建议如何做吗?我在下面基于我们构建的其他一些项目进行了尝试，但从未调用makefile.我要做的就是调用wvdial的makefile，并将二进制文件包含在我们构建的.deb包中.

I have an existing project (wvdial) that has a working makefile. I'm trying to integrate it into our main build process which uses CMake. Can anyone advise on how to do this? I made an attempt below based on some of the other projects we build, but the makefile is never called. All I want to do is call the makefile for wvdial and include the binary in the .deb package we build.

谢谢你， 肖恩

    cmake_minimum_required(VERSION 2.6)

    SET(COMPONENT_NAME roots-vendor-wvdial)

    SET(DEBIAN_PACKAGE_VERSION 1.6.1)

    SET(WVDIAL_SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR})
    SET(WVDIAL_BINARY_DIR ${CMAKE_CURRENT_BINARY_DIR})
    SET(WVDIAL_INSTALLED ${CMAKE_CURRENT_BINARY_DIR})

    ADD_CUSTOM_TARGET(
        wvdial ALL
        DEPENDS ${WVDIAL_INSTALLED}
    )

    IF (${ROOTS_TARGET_ARCHITECTURE} STREQUAL "armhf")
       SET(TARGET_FLAG "--host=arm-linux-gnueabihf")
    ENDIF()

    ADD_CUSTOM_COMMAND(

推荐答案

看看这将向您的CMake项目添加一个虚拟目标，该目标负责构建依赖关系.该命令非常复杂，并支持许多您可能不需要的东西. Kitware(CMake背后的公司)做了一个名为的不错的帖子前一阵子用CMake 2.8构建外部项目 解释了该命令的基本用法.

This will add a dummy target to your CMake project that is responsible for building the dependency. The command is quite complex and supports a lot of stuff that you probably won't need in your case. Kitware (the company behind CMake) did a nice post called Building External Projects with CMake 2.8 a while back explaining the basic use of that command.
