Question

我来自mechE背景，所以我可能会遗漏一些完全无足轻重的东西。我在mac（OS X 10.7 Lion）上使用this使用Unix makefile安装了openCV2.4.1。每次正确使用make和sudo make install，所有.dylib文件都在 lib 文件夹中，但我找不到头文件（“cv.h”等）。）任何地方。 include 文件夹只有cmake_install.cmake，Makefile文件和 CMakeFiles 文件夹。

我之前通过自制程序安装了openCV 2.3.1，并且标题都在include中，因此我必须在库搜索路径中将该路径添加到XCode。现在我不确定如何在没有它的情况下使用该库......？

修改的

我正在使用CMake 2.8.4 GUI。它指定“源代码在哪里”和“在哪里构建二进制文件”。我正在查找我为“在哪里构建二进制文件”指定的文件夹。既然你提到了它，我检查了源代码文件夹并找到了标题，但当然没有.dylib文件....

无论如何，我再次运行CMake（到另一个二进制文件夹，但应该是相同的输出）来获取输出，这里是：

Configuring done

Answer 1

从您的CMake输出：

安装路径：/ usr / local

这意味着在执行make install后，OpenCV标头将被复制到/usr/local/include/

要更改此位置，您可以将CMAKE_INSTALL_PREFIX CMake变量的值设置/修改为所需位置。

在OS X上使用CMake构建openCV 2.4.1时的标题在哪里？
