I can't use openMP in nim_2.0, and it needs to put dll files ,like libgomp-1, the same folder to built exe file to execute it.

Hello, I've been trying to use OpenMP in windows,nim 2.0.8, but some errors occurred.

Firstly, it can't be built in nim 2.0.
I tryed to build examples/ex02_omp_parallel_for.nim, but gcc couldn't built it.
This is the error log.
C:\Users\User\nimcache\ex02_omp_parallel_for_r\@mex02_omp_parallel_for.nim.c: In function 'doOp__ex485095omp95parallel95for_u5':

And this is c file.
@mex02_omp_parallel_for.nim.c.txt

I can build it in version 1.6 or lower. But there is the other problem.

Second, to run a built exe, it must put dll files in the same folder as the exe.
When I try to execute the exe, it says "The code execution cannot proceed becouse libgomp-1. dll was not found. Reinstalling the program may fix this problem.".
I was able to fix it by copying the dll files, which are libgomp-1.dll, libwinpthread-1.dll, libdl.dll and libgcc_s_seh-1.dll, to the folder.
I suspect that these libraries weren't linked statically at compile time.

Could you tell me how to fit them?
