How to Check Windows Version In Cmake?

In CMake, you can check the Windows version by using the CMAKE_HOST_SYSTEM_VERSION variable. This variable provides a string representing the version of the host operating system. You can use this variable in your CMake scripts to perform version-specific tasks or configurations based on the Windows version. It is recommended to check the Windows version before executing any platform-dependent code to ensure compatibility and prevent errors.

How to extract the Windows version details in CMake for troubleshooting purposes?

To extract the Windows version details in CMake for troubleshooting purposes, you can use the following CMake code snippet:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

# Check if the system is Windows
if(WIN32)
    # Get the Windows version details
    execute_process(
        COMMAND ver
        OUTPUT_VARIABLE WINDOWS_VERSION
    )

    message("Windows version: ${WINDOWS_VERSION}")
endif()

This code snippet first checks if the current system is Windows using the WIN32 variable. If the system is Windows, it then uses the execute_process command to run the ver command, which outputs the Windows version details. Finally, the code displays the Windows version details using the message command.

You can include this code snippet in your CMakeLists.txt file or in a specific CMake script where you need to extract the Windows version details for troubleshooting purposes.

How to integrate the Windows version check into a larger CMake project?

To integrate the Windows version check into a larger CMake project, you can follow these steps:

1. Create a CMake script file (.cmake) that checks for the Windows version using the command below:

1
2
3
4
5
6
7
8
9

if (WIN32)
  if (CMAKE_SYSTEM_VERSION EQUAL "10.0.19041")
    message(STATUS "Windows 10 version 2004 detected")
  elseif (CMAKE_SYSTEM_VERSION EQUAL "10.0.18362")
    message(STATUS "Windows 10 version 1903 detected")
  else()
    message(WARNING "Unsupported Windows version")
  endif()
endif()

1. Add the script file to your CMake project by including it in your CMakeLists.txt file using the include() command:

1

include(WindowsVersionCheck.cmake)

1. Run CMake to generate the build files for your project, and the Windows version check will be executed during the configuration process.
2. When building your project, you will see the messages indicating the detected Windows version. You can then use this information to adjust your project's configuration or behavior accordingly.

By following these steps, you can easily integrate the Windows version check into a larger CMake project.

How to verify the Windows version in CMake on a desktop PC?

You can verify the Windows version in CMake on a desktop PC by using the if statement to check the version of the Windows operating system. Here is an example CMake script that checks for Windows 10:

1
2
3
4
5
6
7

if (WIN32)
    if (CMAKE_SYSTEM_VERSION MATCHES "10.*")
        message("Windows 10 detected.")
    else()
        message("Windows version is not 10.")
    endif()
endif()

You can modify the script to check for different versions of Windows by changing the version number in the MATCHES expression. You can also use other system variables like CMAKE_SYSTEM_VERSION and CMAKE_SYSTEM_NAME to get more information about the operating system.
