Could not find a package configuration file provided by "pcl_conversions" with any of the following names

This error usually occurs when you try to build a package that depends on the PCL library and the PCL library is not installed or not properly configured on your system.

To solve this issue, you need to make sure that you have installed the PCL library and all its dependencies on your system. You can do this by running the following command in your terminal:

sudo apt-get install libpcl-dev

If you have already installed the PCL library but still facing the same issue, you can try running the following command:

sudo ldconfig -v | grep pcl

This command will show you the paths where the PCL library is installed. If the paths are not correct, you need to update the LD_LIBRARY_PATH environment variable to include the correct paths.

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

After updating the LD_LIBRARY_PATH environment variable, try building your package again.
