installing development version of cocotb

I am trying to get my cocotb work with commercial simulators (either modelsim or activeHDL) and I would appreciate if someone could help me get them up and running.

I have a Windows machine where I have installed MSYS2 and anaconda3 from where I can install cocotb. I don't have problem installing (I presume stable) cocotb with pip install cocotb through anaconda prompt, however, when I want to install the development version of cocotb through pip install https://github.com/cocotb/cocotb/archive/master.zip I run into trouble. Initially, the installation complained about visual studio c++14 not being installed. I decided to install visual Studio build tools and hope it will install but then the installation failed due to following error

  building 'cocotb\libs\libcocotbutils' extension

  ----------------------------------------

Is this a problem with cocotb's development version or do I miss something? how can I force cocotb use msys2 build tools instead of visual studio's?

PS. The reason I am trying to install the development version is because of activehdl.

You need set MinGW as the default compiler one way is to:

pip install --global-option build_ext --global-option --compiler=mingw32 https://github.com/cocotb/cocotb/archive/master.zip

More info: How to use MinGW's gcc compiler when installing Python package using Pip?

I will try to add this to the documentation.
