If you want a more portable solution you may use "cmake -E" commands
instead of native tar & rm.

add_custom_target(bindist
    COMMAND ${CMAKE_MAKE_PROGRAM} -C ${CMAKE_BINARY_DIR} package
    COMMAND ${CMAKE_COMMAND} -E tar czf
${CMAKE_BINARY_DIR}/${FLAVOR_PACKAGE_NAME}.tar.gz
${FLAVOR_PACKAGE_NAME}
    COMMAND  ${CMAKE_COMMAND} -E remove -f ${FLAVOR_PACKAGE_NAME}.tar.gz
    WORKING_DIRECTORY
${CMAKE_BINARY_DIR}/_CPack_Packages/${CMAKE_SYSTEM_NAME}/TGZ
 )
