Im running OpenFOAM 2112 with wsl Ubuntu 20.04

When im trying to decompose with scotch method, terminal say scoth not installed.

Code:
                                                                                                                                                                                                                                          
 Calculating distribution of cells

Attempted to use <scotch> without the scotchDecomp library loaded.                                                                                                                                                                           
This message is from the dummy scotchDecomp stub library instead.                                                                                                                                                                                                                                                                                                                                                                                                                         Please install <scotch> and ensure libscotch.so is in LD_LIBRARY_PATH.                                                                                                                                                                       
The scotchDecomp library can then be built from src/parallel/decompose/scotchDecomp.                                                                                                                                                        
Dynamically loading or linking this library will add <scotch> as a decomposition method.
but i already install it frome third party
The LD_LIBRARY_PATH have libscotch.so
Code:
echo $LD_LIBRARY_PATH  
/home/hiep/OpenFOAM/hiep-v2112/platforms/linux64GccDPInt32Opt/lib:
/home/hiep/OpenFOAM-v2112/site/2112/platforms/linux64GccDPInt32Opt/lib:

/usr/local/lib/
and here is my libscotch.so path:
Code:
 find -name libscotch.so                                                                                                                                                                                              
./home/hiep/ThirdParty-v2112/platforms/linux64GccDPInt32/lib/libscotch.so                                                                                                                                                                    
./home/hiep/ThirdParty-v2112/platforms/linux64GccDPInt32/lib/sys-openmpi/libscotch.so
