windows报错 CMake Error at PCL can not be found on this machine

这个错误通常是由于CMake在构建过程中无法找到PCL库而引起的。PCL是一个开源的点云处理库,需要安装并配置它才能在CMake中找到它。
要解决这个问题,可以按照以下步骤操作:
1. 确保已经安装了PCL库。您可以从PCL官方网站或其他来源下载并安装PCL库。
2. 配置PCL库的路径。您需要在CMakeLists.txt文件中添加以下代码,以指定PCL库的路径:
set(PCL_DIR "/path/to/pcl/installation")
其中“/path/to/pcl/installation”是PCL库的安装路径。请根据您自己的情况进行替换。
3. 重新运行CMake并生成项目。现在,CMake应该能够找到PCL库并成功构建项目。
如果仍然遇到问题,请确保您的环境变量中包含了PCL库的路径,并检查您的CMakeLists.txt文件是否正确配置了PCL库的路径。

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.
PCL can not be found on this machine 怎么解决
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。
