Linking third party library not found

Greetings, I have been trying for a few days to compile a third party lib file to the matlab mex files on windows 10, matlab v2020a
The third party library is sparse solver pardiso: https://pardiso-project.org/, this library comes with its own .lib files for the underlying pardiso solver routines, as well as its own mex cpp bindings. I am finding that compilation goes down successfully, but calling any of the resulting mexw64 files yields
Invalid MEX-file 'pardiso_intel_compiler_Windows\pardiso-matlab-mex\pardisoinit.mexw64': The specified module could not be found.
I've isolated the source to a subroutine call in one of the mex cpp files:
pardisoinit_(pt,&mtype,&solver,iparm,dparm,&error); // pardisoinit_ not being linked correctly?
This function should supposedly be in the static library (-lpardiso) that I link against:
mex(['-L' 'C:\Program Files\MATLAB\R2020a\extern\lib\win64\microsoft'],...
['-L' '.'], '-lpardiso',...
['-L' 'C:\MinGW\bin'], '-lmwlapack', '-lmwblas',...
['-L' 'C:\Users\jeremy\Desktop\pthreads-w32-2-9-1-release\Pre-built.2\lib\x64'], '-lifcoremt',...
['-L' 'C:\Program Files (x86)\IntelSWTools\parallel_studio_xe_2020.1.086\compilers_and_libraries_2020\windows\compiler\lib\intel64_win'],...
'-lpthreadVC2',...
'-lm', '-output', name,...
'common.cpp', 'matlabmatrix.cpp', 'sparsematrix.cpp', 'pardisoinfo_test.cpp',...
[name '.cpp']);
and is declared in the corresponding header file as
// External Fortran routines defined in the PARDISO dll.
extern "C" int pardisoinit_(void *, int *, int *, int *, double *, int *);
extern "C" int pardiso_(void *, int *, int *, int *, int *, int *,
void *, int *, int *, int *, int *, int *,
int *, void *, void *, int *, double *);
I can't seem to figure out where to go from here, any help would be much appreciated!
Thanks, Jeremy

Can you use loadlibrary( ) to see if MATLAB sees those functions in the library? Can you try UPPERCASE for the prototype names? Maybe the Fortran compiler converted the names to uppercase.
