Ubuntu下打包Qt共享库时mentorsmsConfig.cmake生成异常求助

我开发了一个Qt共享库，希望打包成Ubuntu可安装的标准库，但在应用中使用find_package(mentorsms REQUIRED)时触发CMake错误，错误指向已安装的mentorsmsConfig.cmake文件，错误信息：

/usr/lib/mentorsms/cmake/mentorsmsConfig.cmake:8: error: configure_file Problem configuring file CMakeLists.txt:18 (find_package)

关键文件目录结构 #

mentorsms
--mentorsmslib-1.0
----debian
------control
------rules
----build
------debugrelease
--------Makefile
--------mentorsmsConfig.cmake
----src
------CMakeLists.txt
------cmake
--------mentorsmsConfig.cmake.in

相关文件内容 #

mentorsmsConfig.cmake.in #

set(PACKAGE_NAME "@PACKAGE_NAME@")
set(PACKAGE_VERSION "@PACKAGE_VERSION@")
set(PACKAGE_STRING "${PACKAGE_NAME} ${PACKAGE_VERSION}")
set(PACKAGE_TARNAME "${PACKAGE_NAME}-${PACKAGE_VERSION}")
set(PACKAGE_BUGREPORT "@PACKAGE_BUGREPORT@")
set(PACKAGE_URL "@PACKAGE_URL@")

configure_file(
  "${CMAKE_CURRENT_SOURCE_DIR}/cmake/mentorsmsConfig.cmake.in"
  "${CMAKE_CURRENT_BINARY_DIR}/mentorsmsConfig.cmake"
  @ONLY@
)

生成后的mentorsmsConfig.cmake #

set(PACKAGE_NAME "")
set(PACKAGE_VERSION "")
set(PACKAGE_STRING "${PACKAGE_NAME} ${PACKAGE_VERSION}")
set(PACKAGE_TARNAME "${PACKAGE_NAME}-${PACKAGE_VERSION}")
set(PACKAGE_BUGREPORT "")
set(PACKAGE_URL "")

configure_file(
  "${CMAKE_CURRENT_SOURCE_DIR}/cmake/mentorsmsConfig.cmake.in"
  "${CMAKE_CURRENT_BINARY_DIR}/mentorsmsConfig.cmake"
  
)

疑问点 #

我暂时不在意变量为空的问题，CMakeLists.txt是Qt共享库项目的默认配置，本以为debuild会自动处理相关变量，但configure_file部分的@ONLY@标记未被正确替换。另外，我的rules文件里包含三个cmake命令，会不会是这些命令导致配置文件生成异常？
