构建MultiTarget-tracker库时出现CMake错误

Question

我正在尝试使用Windows中的CMake构建Multitarget-tracker。最初我在下面发出了这个警告：

You should manually point CMake variable OpenCV_DIR to your build of OpenCV library.
Call Stack (most recent call first):
  CMakeLists.txt:57 (find_package)

我手动指出了OpenCV库的构建版本目录，并尝试构建。我在建造时提到了link。我现在收到这个警告：

CMake Warning at CMakeLists.txt:23 (FIND_PACKAGE):
Found package configuration file:
  C:/OpenCV/opencv/build/x86/vc12/lib/OpenCVConfig.cmake
but it set OpenCV_FOUND to FALSE so package "OpenCV" is considered to be NOT FOUND.

我尝试检查OpenCV_FOUND变量，但在我再次按'configure'后，它会自动取消选中。

Answer 1

您不应该手动检查OpenCV_FOUND：它是由OpenCVConfig.cmake设置的变量，用于告诉CMake是否找到了OpenCV。

它设置为FALSE的事实是根据软件包安装OpenCV无效的标志。正确安装OpenCV是解决方案。
