VUnit based project runs error on Windows due to mkdir -p

[pintert3]

Describe the bug
When trying to run a project whose sources are got from a vunit file, an error is thrown when trying to create directories:

2023-10-02 23:22:13.986 [info] "Creating libraries directories"

2023-10-02 23:22:13.989 [info] mkdir -p lib

2023-10-02 23:22:14.015 [info] mkdir -p vunit_lib

2023-10-02 23:22:14.038 [info] A subdirectory or file -p already exists.
Error occurred while processing: -p.

2023-10-02 23:22:14.042 [info] make: *** [make_libraries_directories] Error 1

I reckon the error is due to the whatever make command is being used, as it doesn't work directly on Windows.

To Reproduce
Create a VUnit run.py, a VHDL file and it's test bench.
Create and an empty project in TerosHDL.
Load source files to the project using VUnit run.py.
Set the testbench as the toplevel and try to run.

Please complete the following information:

• Windows 11
• VSCode version 1.82.3

For windows CMD and Powershell, the -p is not necessary

Having the same issue here.
I'm also using Windows (Win10). I have everything perfectly installed (Check dependencies passes without any errors).

In my case I am trying a "GHDL"-Run with the "half_adder" example.
When compiling the two source files "half_adder.vhd" and "half_adder_tb.vhd" into library "work", then everything is fine.
But if I try to introduce some kind of library (e.g. compiling "half_adder.vhd" into "mylib", then there is the same error as described above.

Regards,
Sebastian

I did some digging earlier and realized it's an issue with edalize. I opened an issue there: olofk/edalize#403. Unfortunately, doesn't seem like they'll fix it soon, so I fixed mine by changing the
"mkdir -p {}".format(lib) in the edalize/ghdl.py with "if not exist {s} mkdir {s}".format(s=lib).

It fixed that particular bug for me, although I found another one related to ghdl failing to find the main vhd tb file I was attempting to simulate

Sorry for being a bit slow here. Looking at the code I wonder if we need the -p switch at all. That would be required to create parent directories, but unless I'm misreading things, the command would always make a single-depth subdir in a known existing directory, right?
