The default generator for CMake in Windows is typically "Visual Studio." This generator allows developers to easily create projects and build executables using the Visual Studio integrated development environment. Other generators, such as "MinGW Makefiles" or "Ninja," can also be used depending on the specific requirements of the project.

How to check the supported generators in CMake for Windows?
To check the supported generators in CMake for Windows, you can run the following command in the command prompt:
1
|
cmake --help
|
This command will display a list of supported generators for your system. In Windows, common generators include Visual Studio, MinGW Makefiles, and Ninja. You can also specify a particular generator when configuring your project by using the "-G" flag followed by the generator name. For example, to generate a Visual Studio project file, you can use the following command:
1
|
cmake -G "Visual Studio 16 2019" path/to/source
|
Replace "Visual Studio 16 2019" with the appropriate generator name based on the output of the cmake --help command.
How to specify a specific generator in CMake for Windows?
To specify a specific generator in CMake for Windows, you can use the "-G" flag followed by the name of the generator you want to use. Here is an example of how you can specify the "Visual Studio 2019" generator:
1
|
cmake -G "Visual Studio 16 2019" path/to/source
|
Replace "Visual Studio 16 2019" with the name of the generator you want to use. Some other common generators for Windows are "Visual Studio 14 2015", "Visual Studio 15 2017", "Ninja", and "MinGW Makefiles". You can find a list of available generators by running:
1
|
cmake --help
|
This will display a list of available generators for your platform. Choose the one that best suits your needs and provide it as an argument to the "-G" flag when generating the build system with CMake.
How to see the available generator options in CMake for Windows?
To see the available generator options in CMake for Windows, you can run the following command in the command prompt:
1
|
cmake --help
|
This will display a list of available generators along with other options and commands supported by CMake. Look for the section titled "Generators" to see the available options for Windows. Some common generators for Windows include "Visual Studio", "Ninja", and "MinGW Makefiles". Choose the appropriate generator based on your specific requirements and build environment.
How to verify the current generator being used by CMake in Windows?
- Open the command prompt in Windows.
- Navigate to the directory where CMake is installed.
- Run the following command to check the generator being used by CMake: cmake --version
- The output will display the version of CMake being used along with the generator being used. For example, it might display "Visual Studio 16 2019 Win64" if Visual Studio 2019 is being used as the generator.
Alternatively, you can check the current generator being used by CMake by opening the CMake GUI and checking the generator selected in the "Generator" drop-down menu.
What is the process for creating a custom generator in CMake for Windows?
Creating a custom generator in CMake for Windows involves the following steps:
- Create a new CMake generator file: Start by creating a new CMake generator file. This file will contain the logic for generating project files specific to your desired build system or IDE. You can use an existing generator file as a template or create one from scratch.
- Define the generator logic: In the generator file, define the logic for generating project files based on the target build system or IDE. This may include specifying project settings, configuring build options, and generating project files in the appropriate format.
- Register the generator: Once you have defined the generator logic, you need to register the custom generator with CMake. This involves adding a call to the cmGlobalGeneratorFactory::RegisterGenerator function in your generator file to register the new generator.
- Build CMake with the custom generator: After registering the custom generator, you will need to build CMake to include the new generator in the list of available generators. This involves building CMake from source code with the custom generator file included.
- Use the custom generator: Once CMake has been built with the custom generator, you can use it to generate project files for your CMake projects on Windows. Specify the custom generator using the -G option when running CMake, e.g., cmake -G CustomGenerator.
By following these steps, you can create a custom generator in CMake for Windows that can generate project files tailored to your specific build system or IDE requirements.
