How to Generate .Msi Installer With Cmake?

To generate a .msi installer with CMake, you can use the CPack module that comes built-in with CMake. CPack allows you to create installers in various formats, including .msi.

To use CPack, you need to add the following lines to your CMakeLists.txt file:

1
2

set(CPACK_GENERATOR "NSIS" "WIX")
include(CPack)

In this example, we are specifying that we want to generate installers using the NSIS and WIX generators. NSIS is used for creating .exe installers, while WIX is used for creating .msi installers.

You can customize the installer settings by adding CPack directives to your CMakeLists.txt file. For example, you can set the package name, version, and install directories.

Once you have configured CPack in your CMakeLists.txt file, you can generate the .msi installer by running the following commands in the build directory:

1
2
3

cmake ..
cmake --build .
cpack

These commands will configure your project, build it, and then create the .msi installer using CPack.

After running these commands, you will find the generated .msi installer in the build directory. You can then distribute this installer to users for installation on Windows systems.

What is the role of WiX in conjunction with cmake for generating .msi installers?

WiX (Windows Installer XML) is a toolset that allows developers to create Windows Installer packages (MSI files) for their software applications. On the other hand, CMake is a cross-platform build system that helps in managing the build process for software applications.

When using WiX in conjunction with CMake for generating .msi installers, the role of WiX is to actually create the MSI package that will be used to install the application on a target system. WiX provides tools and libraries for building MSI packages, including creating installation sequences, specifying dependencies, and customizing the installation process.

CMake, on the other hand, can be used to generate the necessary files and configurations required by WiX to build the MSI package. This includes specifying the installation directories, files to be included in the package, version information, and other settings that are needed for the installation process.

By combining WiX and CMake, developers can automate the process of creating MSI installers for their software applications and ensure a smooth installation experience for their users on Windows systems.

How to customize the installation process in a .msi installer using cmake?

To customize the installation process in a .msi installer using CMake, you can use the CPack package generator provided by CMake. CPack allows you to create customized installation packages, including .msi installers, with specified installation options.

Here are the steps to customize the installation process in a .msi installer using CMake:

1. Add CPack configuration to your CMakeLists.txt file:

1
2
3
4
5
6
7

set(CPACK_PACKAGE_NAME "MyProject")
set(CPACK_PACKAGE_VERSION "1.0.0")
set(CPACK_PACKAGE_VENDOR "MyCompany")

set(CPACK_GENERATOR "WIX")

include(CPack)

1. Specify installation options in a CPackConfig.cmake file: Create a CPackConfig.cmake file in your project directory with the following content to specify installation settings such as installation directories, desktop shortcuts, etc.

1
2
3
4

set(CPACK_PACKAGE_EXECUTABLES "MyProject" "MyExecutable")

set(CPACK_WIX_PROPERTY_APP_MANUFACTURER "MyCompany")
set(CPACK_WIX_PROPERTY_APP_VERSION ${CPACK_PACKAGE_VERSION} )

1. Add additional customization options: You can customize the installation process further by setting additional CPack variables in your CMakeLists.txt file or CPackConfig.cmake file. For example, you can customize the installation directory, add desktop shortcuts, create Start menu entries, etc.
2. Generate the installer: Run CMake to configure your project and generate the installer.

1
2

cmake ..
cmake --build . --config Release

1. Run CPack to create the installer:

1

cpack -C Release

1. Your customized .msi installer should be generated in the build directory. You can run the installer to install your project with the specified customization options.

By following these steps, you can customize the installation process in a .msi installer using CMake and CPack.

What are the best practices for creating a .msi installer with cmake?

When creating a .msi installer with cmake, it is important to follow best practices to ensure a smooth and successful installation process. Some best practices for creating a .msi installer with cmake include:

1. Use the CPack tool: CMake provides a built-in tool called CPack for packaging projects into different formats including .msi installers. CPack simplifies the process of creating installers and provides a lot of flexibility and customization options.
2. Define installation components: When creating a .msi installer, it is important to define installation components such as files, directories, shortcuts, registry keys, etc. This allows users to select which components to install and provides more control over the installation process.
3. Include a license agreement: It is a good practice to include a license agreement with your installer to ensure that users are aware of the terms and conditions of using your software.
4. Test the installer: Before releasing the installer to users, it is important to thoroughly test it on different systems to ensure that it works as expected. This includes testing the installation process, uninstallation process, and verifying that the installed software functions correctly.
5. Provide documentation: Include documentation with your installer that explains how to install and use the software. This can help users troubleshoot any installation issues and ensure a smooth installation process.
6. Sign the installer: When distributing your .msi installer, it is recommended to sign it with a digital certificate to verify its authenticity and ensure that users can trust the source of the installer.

By following these best practices, you can create a reliable and user-friendly .msi installer for your software project.

How to sign the .msi installer with a digital certificate through cmake?

Signing an .msi installer with a digital certificate through CMake can be achieved by following these steps:

1. Obtain a digital certificate from a reputable Certificate Authority (CA) such as VeriSign, Thawte, or Comodo.
2. Generate a private key and a Certificate Signing Request (CSR) using a tool like OpenSSL.
3. Submit the CSR to the CA and obtain a digital certificate.
4. Once you have the digital certificate, create a property sheet file (.props) that includes the paths to the digital certificate and private key files. This file will be used by CMake to sign the installer.
5. In your CMakeLists.txt file, include the property sheet file using the include_external_msproject command.
6. Add the SIGN property to your add_custom_command or add_custom_target for the .msi installer target, and set it to the name of the property sheet file.
7. Run CMake to generate the Visual Studio solution and build the .msi installer. The installer will be signed with the digital certificate specified in the property sheet file.

By following these steps, you can successfully sign your .msi installer with a digital certificate through CMake.
