CPACKPACKAGENAME
CPACK_PACKAGE_NAME is a variable in CPack, the packaging tool integrated with CMake. It defines the base name used for the generated package files and their internal metadata across supported packagers such as DEB, RPM, TGZ, MSI and NSIS. Note that CPACKPACKAGENAME is not a standard variable in CPack; the correct variable is CPACK_PACKAGE_NAME. If CPACK_PACKAGE_NAME is not set, CPack typically uses the CMake project name (PROJECT_NAME) as a default.
The value is usually defined in the CMakeLists.txt before invoking include(CPack), for example to align packaging
CPACK_PACKAGE_NAME is supported by all standard CPack generators; however, exact effects may vary by format, so
