如何列出所有 CMake 构建选项及其默认值? [英] How to list all CMake build options and their default values?

问题描述

如何在命令行中列出 cmake 默认构建选项?
我需要从源代码构建 OpenCV 库.在此之前，我想知道默认构建设置是什么.

How can I list cmake default build option in command-line?
I need to build OpenCV libraries from source. Before that, I want to know what are the default build settings.

推荐答案

cmake -LA

要列出所有 option( 和 set( CACHE (缓存) 变量，请执行以下操作:

To list all option( and set( CACHE (cached) variables do:

mkdir build
cd build
cmake ..
cmake -LA | awk '{if(f)print} /-- Cache values/{f=1}'

示例标准输出:

AUTOGEMM_ARCHITECTURE:STRING=Hawaii
BLAS_DEBUG_TOOLS:BOOL=OFF
BLAS_DUMP_CLBLAS_KERNELS:BOOL=OFF
BLAS_KEEP_KERNEL_SOURCES:BOOL=ON
BLAS_PRINT_BUILD_ERRORS:BOOL=O

-A 开关还显示选项 标记为高级，因此您在随意浏览最有用的选项时可能希望省略它.

The -A switch also show options marked as advanced, so you will likely want to omit it when casually browsing the most useful options.

ccmake ncurses

ccmake ncurses

sudo apt-get install cmake-curses-gui
ccmake ..
