Cannot build via scripts/conda_build.bat?

[snyang]

I met the following error via running scripts/conda_build.bat, any idea to resolve it?

Added file:///C:/Users/HUAWEI/.conda/envs/pclpy2/conda-bld/pclpy_1673777755063/work to build tracker 'C:\\Users\\HUAWEI\\AppData\\Local\\Temp\\pip-build-tracker-smcdp8_3'

  Perhaps you should add the directory containing `pcl_2d-1.9.pc'
  to the PKG_CONFIG_PATH environment variable
