按照教程：http://blog.csdn.net/wanghelou123/article/details/52549335
在iTOP-4412上安装OpenCV出错，进行到进入release目录后使用

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..

时，cmake报错了。

CMake Error at CMakeLists.txt:29 (cmake_minimum_required):                      

  CMake 2.8.12.2 or higher is required.  You are running version 2.8.7          

                                                                                

                                                                                

-- Configuring incomplete, errors occurred!

看样子说是需要2.8.12.2以上版本才能行，可是后一句又说我运行的版本是2.8.7，这不是已经符合了吗？
然后又查看了CMakeCache文件：

# This is the CMakeCache file./Desktop/opencv-3.3.1/release# cat CMakeCache.txt 

# For build in directory: /root/Desktop/opencv-3.3.1/release                    

# It was generated by CMake: /usr/bin/cmake                                     

# You can edit this file to change values found and used by cmake.              

# If you do not want to change any of the values, simply exit the editor.       

# If you do want to change a value, simply edit, save, and exit the editor.     

# The syntax for the file is as follows:                                        

# KEY:TYPE=VALUE                                                                

# KEY is the name of a variable in the cache.                                   

# TYPE is a hint to GUI's for the type of VALUE, DO NOT EDIT TYPE!.             

# VALUE is the current value for the KEY.
