I am using Simulink Coder to compile my simulink model into a shared library (embedded target) which I then try to load into MATLAB using coder.loadlibrary. Upon executing the following command, I get an error:

libModelPath    = fullfile(pwd, 'mylib_ert_shrlib_rtw');
libSimulinkPath = fullfile(matlabroot, 'simulink', 'include');
hfile = fullfile(libModelPath, 'mylib.h');
coder.loadlibrary('mylib_win64', hfile, ...
'includepath', libModelPath, ...
'includepath', libSimulinkPath, ...
'mfilename', 'testfile', ...
'alias', 'mylibrary')

The error I get is:

coder.loadlibrary('mylib, hfile)
Error using loadlibrary (line 447)
Failed to preprocess the input file.
 Output from preprocessor is:'mylib.h
C:\Users\[...]\'mylib_ert_shrlib_rtw\'mylib.h(28)
: fatal error C1083: Cannot open include file: 'nesl_rtw.h': No such file or directory

Lines 18-30 of mylib.h:
