2. 通过cmake添加macro宏定义 出入到源文件,例如在编译opencv/caffe的时候,我们通过cmake -DUSE_CUDA=ON/OFF来确定,是否使用cuda. 问题cmake中如何实现上述两个功能的呢? 至于问题1: 我们可能想到直接在头文件中定义,这样也可以,但是如果直接在cmake中定义,然后传递给程序读取生成更加灵活。 至于问题2: 可以在...
在Path中添加: D:\opencv310_CUDA\install\x64\vc12\bin; (其实我在用户的环境变量中也加了一条,不过貌似加不加都行) 配置完环境变量,重启或注销才能生效 2、配置VS的项目属性: 新建一个控制台应用程序,然后在项目名称上右键->属性: 然后: (路径以你的电脑实际为准) ...
如果需要我们的CMakeLists有一定的自由配置,比如,我们需要开启CUDA的支持,或者关闭某个功能。如果功能项比较多的话,每次增加功能或者修改,直接在CMakeLists中写一堆代码命令会很麻烦。 在这种情况下的话,最好是另外创建一个名为config.cmake的文件,这个文件中填写了我们的配置信息(举个例子): ...
