After this, one can build the project using the `IfcOpenShell.sln` file in the build folder. Build the `INSTALL` project

expect `%1` and `%2` in same fashion as above and possible extra parameters are passed for the `MSBuild` call. The project will
be installed to `installed-vs<VERSION>-<ARCHITECTURE>\` folder in the project's root folder and the required IfcOpenShell-Python
parts are deployed to the `<PYTHONPATH>\Lib\site-packages\` folder.
**Note:** All of the dependencies are build as static libraries against the static run-time allowing the developer
to effortlessly deploy standalone IFCOS binaries.
Using an already existing Python installation
---------------------------------------------
Let's say you have already installed 64-bit Python 3.5.1 to `C:\Python3`.
Before building the dependencies, disable the script from installing Python:
```
> set IFCOS_INSTALL_PYTHON=FALSE
> buid-deps.cmd
```
After bulding the dependencies, create BuildDepsCache file to `IfcOpenShell\win` which tells the used Python version and intallation directory:
```
> echo PY_VER_MAJOR_MINOR=35> BuildDepsCache-x64.txt
> echo PYTHONPATH=C:\Python3>> BuildDepsCache-x64.txt
```
After this you should be able to run `run-cmake.bat` normally. If using 32-bit Python, the name of the file must be `BuildDepsCache-x86.txt`.
