Question

我尝试编译此存储库link，但是我陷入了CMake错误：找不到 ann_LIBRARIES 。在内部网中搜索时，我发现了我构建的ANN link，但我不知道如何在Cmake文件中给出绝对路径。而且我还安装了libflann1.9和libflann-dev，但仍然遇到相同的问题。

我有ubuntu 18.04和qt5，安装了boost lib，blas＆lapack和libpng库。

最后，我能够编译代码库

我的程序如下：

首先，我尝试在ubuntu 18.04中编译源代码，但遇到了很多错误，因此我在ubuntu 14.04（码头工人）中进行了尝试。
我安装了作者提到的必需软件包。
现在我遇到了an_LIBRARIES问题，为此，我从link下载了ANN库，并只需从an_1.1.2文件夹内执行 make linux-g ++ 进行构建
现在可以使用ANN库了。之后，为避免在构建过程中出现an_LIBRARIES问题，我们应该从终端cmake -Dann_LIBRARIES=/home/ann_1.1.2/lib/libANN.a ..执行命令
到目前为止，我已经成功构建了项目。现在是时候使用make命令来编译代码了，我又遇到了ANN/ANN.h: No such file or directory错误，我通过提供每个发生错误的文件的绝对路径#include </home/ann_1.1.2/include/ANN/ANN.h> //approximate) nearest neighbor来解决了这个错误。显然提供绝对路径不是一个好主意。就这样

希望这对某人有帮助。
