* Unzip it in the `gmsh-api` folder
* Rename `gmsh-4.5.2-Windows64-sdk` into `gmsh-sdk`
* Double click on `envs\win-mingw64.cmd`
* Create a build folder:
* Open VS Code and load the `gmsh-api` folder.
* In the terminal of VS Code, install gmsh-sdk using the script `get_gmsh.cmd` (only once per working copy of the repository)
```
get_gmsh.cmd
```
* Add MinGW and gmsh-sdk to your environment by running this script (it should be done each time you re-open VS Code or a new terminal):
```
envs\win-mingw64.cmd
```
* Then, in the same terminal, create a build folder:

mkdir build

# Note about the environment scripts
The scripts in the `gmsh-api/envs/` folder add several folders to 3 environment variables so that the system and cmake find the compiler and the libraries correctly:
*`PATH`: this variable should contain the location of the folder of your `g++` compiler, of `gmsh.exe` and its shared library (`gmsh.dll/so/dylib`),
*`LIB`: points to the path of the folder containing `gmsh.lib` (windows) or `gmsh.so` (linux) or `gmsh.dylib` (macOS),
*`INCLUDE`: points to the path of the folder containing the header `gmsh.h`.
Instead of using these scripts which should be loaded each time you start a new terminal, these 3 variables can be defined in your global user environment once and for all.
This is done by going to "Settings" on Windows, and typing "env" in the search bar. Then choose the appropriate menu ("modify environment variables").
On Linux/macOS, you can add/modify environment variables by editing `~/.bashrc` (just copy & paste the contents of `envs/linux-macOS.sh`).
