CPACKPACKAGECONTACT

CPACKPACKAGECONTACT is a variable used within the CMake build system, specifically in the CPack component. CPack is a tool for generating installers for projects built with CMake. The CPACKPACKAGECONTACT variable is intended to store contact information for the creator or maintainer of the package. This information is then typically included in the generated installer, providing users with a way to get in touch for support, bug reports, or other inquiries.

When defining the CPack configuration within a CMakeLists.txt file, developers can set CPACKPACKAGECONTACT to a string value. This string can contain email addresses, website URLs, or any other relevant contact details. The exact way this information is presented in the final installer depends on the installer generator being used by CPack (e.g., NSIS, DMG, RPM). For instance, it might appear on an "About" page or in a README file bundled with the installation.

Setting CPACKPACKAGECONTACT is a good practice for software distribution as it facilitates communication between users and developers. It promotes transparency and helps to build a community around the software. If this variable is not set, the contact information field in the installer will likely be left blank or may display a default message, depending on the CPack generator.
