这个问题通常是由于 PCL (Point Cloud Library)未正确安装或未正确配置环境变量引起的。您可以尝试以下步骤来解决此问题:
1. 检查 PCL 是否已正确安装并位于正确的路径中。您可以在终端中输入 `pcl-config --version` 命令来检查 PCL 安装是否成功。如果未安装,请参考 PCL 的安装指南进行安装。
2. 如果 PCL 已正确安装,请检查环境变量是否正确配置。在 Linux 系统中,您可以将 PCL 的路径添加到环境变量中。例如,您可以在 `.bashrc` 文件中添加以下行:
```
export PCL_ROOT=/path/to/pcl
export PATH=$PATH:$PCL_ROOT/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PCL_ROOT/lib
```
3. 如果您使用的是 CMake 进行编译,请确保已正确配置 PCL 的路径。您可以通过在 CMakeLists.txt 文件中添加以下行来配置 PCL 的路径:
```
find_package(PCL 1.7 REQUIRED)
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
```
希望这些步骤能够帮助您解决问题。

PCL can not be found on this machine
这个错误消息说明你的机器上没有安装 PCL (Point Cloud Library) 库。PCL 是一个广泛使用的点云处理库,它提供了许多点云相关的功能,比如点云滤波、点云配准、曲面重建等等。如果你在使用某个需要 PCL 库的软件或者工程时遇到了这个错误,那么你需要先在你的机器上安装 PCL 库才能正常使用。
安装 PCL 库的具体步骤可以因操作系统和版本而异,可以参考 PCL 官方文档或者相关社区的教程。一般来说,你可以使用系统包管理器来安装 PCL 库,比如在 Ubuntu 下可以使用以下命令安装:
```
sudo apt-get install libpcl-dev
```
安装完成后,重新编译和运行你的软件或者工程即可。
CMake Error at PCL can not be found on this machine
As an AI language model, I do not have access to your machine to provide a specific solution to your problem. However, here are some general troubleshooting steps that you can follow:
1. Make sure that PCL is installed on your machine. You can check this by running the following command in your terminal:
```
pcl-config --version
```
If PCL is not installed, you can download it from the PCL website.
2. Check if PCL is included in your CMakeLists.txt file. You should have the following lines in your file:
```
find_package(PCL 1.7 REQUIRED)
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
```
3. Make sure that the PCL library path is added to your LD_LIBRARY_PATH environment variable. You can do this by adding the following line to your .bashrc file:
```
export LD_LIBRARY_PATH=/path/to/pcl/lib:$LD_LIBRARY_PATH
```
Replace /path/to/pcl/lib with the actual path to the PCL library on your machine.
4. If you have installed PCL in a non-standard location, you can specify the path to the PCL library in your CMakeLists.txt file by adding the following line:
```
set(PCL_DIR /path/to/pcl)
```
Replace /path/to/pcl with the actual path to the PCL library on your machine.
5. If none of the above steps work, try reinstalling PCL and make sure that all dependencies are installed.
