为什么不是命令"cmake".生成一个makefile？

Question

我cmake .在终端运行,它说它生成了一些东西,然后我跑了make,它说

make: *** No targets specified and no makefile found.  Stop.

我猜我错过了我需要做的其他事情,但我无法弄清楚是什么.它应该创建一个make文件,然后我可以构建然后安装.

如果我太模糊,请告诉我我还能为这个问题添加更多内容.

$ cmake .

看来CMake默认在Mac上生成一个XCode项目.CMake freeglut.xcodeproj与所有支持文件一起生成.

最好cmake从空目录运行,这样你就可以看到它在运行时的实际功能.

要生成一个makefile(并创建一个构建目录),请执行

mkdir -p cmake-build && cd cmake-build
cmake .. -G"Unix Makefiles"

然后它应该生成一个Makefile.
