Compiler mex errors

[PanosSken]

Hello. I am trying to use hpipm in Matlab and Simulink. I am using Matlab 2021b and I have installed Visula Studio 2022 at my computer. I have followed the instruction of the installation but I face some problems. The blasfeo installation and build proccess has been done without problems. When I try to build hpipm and run the command: cmake --build, I get the following error:

C:\myfiles\hpipm\examples\c\example_d_ocp_qp.c(45,10): fatal  error C1083: Cannot open include file: 'sys/time
.h': No such file or directory [C:\myfiles\hpipm\build\examples\c\example_d_ocp_qp.vcxproj]
  getting_started_data.c
C:\myfiles\hpipm\examples\c\data\getting_started_data.c(100,29): error C2059: syntax error: '}' [C:\myfiles\hpipm\build\examples\c\example_d_ocp_qp.vcxproj].

This problem started popping up after I tried to rebuild hpipm to overcome the following two problems.

1. In order to use hpipm in Matlab, I run env.m and then hpipm/interfaces/matlab_octave/compile_mex_all.m. After running th file the following error pops up:

Building with 'MinGW64 Compiler (C)'.

collect2.exe: error: ld returned 1 exit status

2. Another error comes up when I follow the instruction in order to use hpipm in Simulink after running hpipm/examples/simulink/make_sfun.m :

Error using mex

C:\myfiles\hpipm\lib\hpipm.lib(hpipm.dir/Debug/timing.obj):(.rtc$IMZ+0x0):

Could you please help me solving this issues?
