CMake is a build system generator that allows you to define and configure your build process. When you specify `Werror` in CMake, it means that you want to treat all warnings as errors during the build process.
To enable treating warnings as errors in CMake, you can use the `CMAKE_C_FLAGS` or `CMAKE_CXX_FLAGS` variables. These variables allow you to specify additional compiler flags for the C and C++ languages, respectively.
Here's an example of how you can enable treating warnings as errors in CMake:
```cmake
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Werror")
```
This line will add the `-Werror` flag to the existing flags in `CMAKE_C_FLAGS`, which will make all warnings treated as errors during the compilation of C code.
Similarly, for C++ code, you can use the following line:
```cmake
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Werror")
```
By adding these lines to your CMakeLists.txt file, you will enable the `-Werror` flag and treat warnings as errors when building your project using CMake.
