CMake：指定构建工具链 [英] CMake: specifying build toolchain

问题描述

CMake非常新，到目前为止，我发现它非常有帮助。我有一套自定义库，我想使用交叉编译为多个平台构建。安装工具链，我可以手工创建 Makefile ，我需要这样做，但我想能够使用CMake。

有没有办法告诉 cmake 哪个工具链要使用，无论是在命令行还是在

www.vtk.org/Wiki/CMake_Cross_Compiling\">在这里：基本上，你定义一个工具链文件，设置的东西像系统名称，路径编译器等。然后调用 cmake ：

  cmake / path / src -DCMAKE_TOOLCHAIN_FILE = / path / to / toolchain / foo-bar-baz.cmake 
  




Very new to CMake, and so far I'm finding it to be extremely helpful. I have a set of custom libraries that I would like to build for multiple platforms using cross-compilation. The toolchains are installed, and I can hand-create the Makefiles that I need to do so, but I would like to be able to make use of CMake.

Is there a way to tell cmake which toolchain to use, either at the command line or in the CMakeLists.txt file?

解决方案

Have a look here: basically, you define a "toolchain file" that sets things like the system name, paths to compilers and so on. You then call cmake like so:

cmake /path/to/src -DCMAKE_TOOLCHAIN_FILE=/path/to/toolchain/foo-bar-baz.cmake
