PCL库——报错解决：安装时遇到的cmake与anaconda的冲突问题

一、报错

CMake Warning at cmake/pcl_targets.cmake:194 (add_library):

  Cannot generate a safe runtime search path for target pcl_io because files

  in some directories may conflict with libraries in implicit directories:

    runtime library [libz.so.1] in /usr/lib/x86_64-linux-gnu may be hidden by files in:

      /home/filex/anaconda3/lib

    runtime library [libfreetype.so.6] in /usr/lib/x86_64-linux-gnu may be hidden by files in:

      /home/filex/anaconda3/lib

    runtime library [libexpat.so.1] in /usr/lib/x86_64-linux-gnu may be hidden by files in:

      /home/filex/anaconda3/lib

    runtime library [libxml2.so.2] in /usr/lib/x86_64-linux-gnu may be hidden by files in:

      /home/filex/anaconda3/lib

    runtime library [libQt5Sql.so.5] in /usr/lib/x86_64-linux-gnu may be hidden by files in:

      /home/filex/anaconda3/lib

    runtime library [libQt5Network.so.5] in /usr/lib/x86_64-linux-gnu may be hidden by files in:

      /home/filex/anaconda3/lib

  Some of these libraries may not be found correctly.

Call Stack (most recent call first):cmake

  io/CMakeLists.txt:331 (PCL_ADD_LIBRARY)

二、原因

找库文件时的路径跑到anaconda那去了。

三、解决办法

打开bashrc，注释掉PATH中包含anaconda的路径，重启终端窗口。
具体步骤：

1. gedit ~/.bashrc
2. 注释掉PATH中包含anaconda的路径
3. source ~/.bashrc
4. 重启终端窗口（一定要重启，不然没效果）
