编译opencv示例：未知的cmake命令ocv_check_dependencies [英] Compiling opencv samples: unknown cmake command ocv_check_dependencies

问题描述

我正在尝试构建与源代码包一起提供的OpenCV示例，并获得以下内容：

  CMakeLists.txt：10（ocv_check_dependencies）：
未知的CMake命令ocv_check_dependencies。 
 

我使用

安装了OpenCV

  cmake。 
 make 
 sudo make install 
  

我有一个教程片段工作我想它是作为一个库正确安装）。但是，编译示例不起作用。

我想我不得不以某种方式配置CMake有ocv_check_dependencies - 但如何？我失去了！

按顺序排列要构建样本，必须通过 -D 提供它来更改cmake的默认配置。我错误的是，我试图在 samples 目录中执行cmake。

正确的构建方式示例调用cmake像这样（从解压缩的归档的根目录下）：

  cmake -DBUILD_SAMPLES。 
  

一个可以继续使用make，make install than。

另请参见常见问题

I am trying to build the OpenCV samples which come with the source package and I get the following:

CMake Error at CMakeLists.txt:10 (ocv_check_dependencies):
  Unknown CMake command "ocv_check_dependencies".

I did install OpenCV using

cmake .
make
sudo make install

and I got a tutorial snippet working (thus I suppose it is installed correctly as a library). However, compiling the samples does not work.

I guess I have to somehow configure CMake to have "ocv_check_dependencies" - but how? I am lost!

解决方案

I got it.

In order to build the samples one has to change the default configuration for cmake by providing it via -D. What I did wrong was that I tried to execute cmake from within the samples directory.

The proper way to build the samples is invoking cmake like so (from within the root directory of the unpacked archive):

cmake -DBUILD_SAMPLES .

which will turn samples ON. One can proceed using make, make install than. The samples can be found in bin after building.
