vl_compilenn directory

[ghost]

I'm trying to run my cnn model on matlab .I think it is not compiling the right directory.
When i compile
CUDA: MEX config file: 'D:\Polyspace\R2020a\toolbox\distcomp\gpu\extern\src\mex\win64\mex_CUDA_win64.xml'
the above directory is configured but the mex file and matconvnet toolbox is in :D:\TADT-master\utils\matconvnet\matlab\mex directory.
Is this why i'm getting the following error?
Error using vl_nnconv
