Note that Ninja runs in parallel by default. Use the ``-j`` flag to change this.
Note that Ninja also runs on Windows. You just need to run ``cmake`` in an
environment where the compiler can be found. If you have Visual Studio
installed it typically ships with a "Developer Command Prompt Window" that you
can use which has the environment variables setup for you.
## NMake
NMake is a build system that ships with Visual Studio. You are advised to use
Ninja instead which is significantly faster due to supporting concurrent
builds. However CMake does support NMake if you wish to use it. Note that
NMake is a single configuration generator so you must set ``CMAKE_BUILD_TYPE``
to set the build type.
Basic usage:
1. Launch the "Developer Command Prompt Windows"
2. Change to the root of the Z3 repository
```
mkdir build
cd build
cmake -G "NMake Makefiles" ../
nmake
```

On the command line these can be passed to ``cmake`` using the ``-D`` option. In ``ccmake`` and ``cmake-gui`` these can be set in the user interface.
Example
```
cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_TRACING=FALSE ../
```
