Cmake falha ao configurar o OpenCV

Question

Estou tentando construir o OpenCV e usá-lo no Qt. Eu instalei todos os pacotes necessários para o OpenCV e Qt, depois disso eu tentei executar também cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local /media/d/Install/opencv-2.4.8 , mas recebi erros:

CMake Error at CMakeLists.txt:70 (message):
  CMake fails to deterimine the bitness of target platform.

    Please check your CMake and compiler installation. If you are crosscompiling then ensure that your CMake toolchain file correctly sets the compiler details.

Answer 1

Eu resolvi isso removendo a pasta de compilação na qual eu havia iniciado o cmake, mas cancelei-o durante a instalação. Agora funciona.
