I follow the instructions from http://nenadbulatovic.blogspot.com/2013/07/configuring-opencv-245-eclipse-cdt-juno.html. When I follow the instructionf of cmake from step 5 to 8, press configure it returns the follow: CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly. Missing variable is: CMAKE_CXX_COMPILER_ENV_VAR CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.

it sounds like it did not find your compiler suite, 'make' and 'g++', so your compiler is not 'on the path'

it complains about missing env vars, CMAKE_CXX_COMPILER_ENV_VAR, CMAKE_CXX_COMPILER

You need to install cmake and mingw if you don't have them. Then set the environment variable for them.
