我需要构建IDS的SimpleStreamer应用

这是SimpleStream的CMakeLists.txt的内容：
project(SimpleStream)
cmake_minimum_required(VERSION 2.8)
aux_source_directory(. SRC_LIST)
add_executable(${PROJECT_NAME} ${SRC_LIST})
target_link_libraries(${PROJECT_NAME} ueye_api ueye_stream)
i将项目的lib和include文件夹复制到系统范围的lib和include：
sudo cp include/ueye_stream.h /usr/local/include/
sudo cp lib/libueye_stream.so.2.0 /usr/local/lib/
我以与/usr/local/lib和Project的lib相同的方式进行了符号链接：
lrwxrwxrwx 1 olga olga 19 июн 21 2016 libueye_stream.so -> libueye_stream.so.2
lrwxrwxrwx 1 olga olga 21 июн 21 2016 libueye_stream.so.2 -> libueye_stream.so.2.0
-rwxr-xr-x 1 olga olga 151018 июн 21 2016 libueye_stream.so.2.0
我在没有任何错误的情况下制作了sudo ldconfig。
我从SimpleStream的build dir做了cmake ..：
-- Configuring done
-- Generating done
-- Build files have been written to: /home/olga/camera/ueye/ueye_stream/ueye_stream_x64/src/SimpleStreamer/build
但是当我继续进行make阶段时，我会遇到很多错误：

好的，在阅读了一些理论材料和"推论思维"（c）之后，我找到了解决方案：
- 我创建了文件夹
/usr/local/lib/ueye_olga - 我将项目的根
lib及其子文件夹中的所有必要库复制到ueye_olga，请参见下面的输出。 - 我删除了不必要的文件，并用链接替换它们（请参见下面的说明）
- 我创建了
/etc/ld.so.conf.d/ueye_olga.conf with path to the/usr/local/lib/ueye_olga`，请参见下文。 - 我制作了
sudo ldconfig - 我检查了
libueye_stream.so是否正确链接（见下文） - 我需要移动
libueye_stream.so，并且它是链接文件夹，我不知道为什么，请参阅下面的错误。 - 再次
sudo ldconfig -
make工作正常

不必要的文件删除：
如果您不创建软链接，则会收到错误，例如：
/sbin/ldconfig.real：/usr/local/lib/ueye_olga/libavcodec.so.56不是 符号链接
原因：
典型的图书馆模块可以将其安装为一个 在几个版本中。通常只安装一个版本， 其他可能的版本表示为指向 安装版本。符号链接是另一个指向 已安装的模块。例如，我有/usr/lib/libstdc so.6.0.10 安装。我也有/usr/liblibstdc .so.6作为符号链接 指向/usr/lib/libstdc so.6.0.10，以便您可以访问libstdc 以任一个名称。
