使用旧的 LibTool 宏

问题描述

我想为我使用 CMake 3 构建的库生成一个 libtool 文件。我发现了这个宏，它对旧版本的 CMake 有帮助：https://gitlab.kitware.com/cmake/community/-/wikis/contrib/macros/LibtoolFile

以下是适用于 CMake 2.8 的代码：

 MACRO(GET_TARGET_PROPERTY_WITH_DEFAULT _variable _target _property _default_value)
   GET_TARGET_PROPERTY (${_variable} ${_target} ${_property})
   IF (${_variable} MATCHES NOTFOUND)
     SET (${_variable} ${_default_value})
   ENDIF (${_variable} MATCHES NOTFOUND)
 ENDMACRO (GET_TARGET_PROPERTY_WITH_DEFAULT)

 MACRO(CREATE_LIBTOOL_FILE _target _install_DIR)
   GET_TARGET_PROPERTY(_target_location ${_target} LOCATION)
   GET_TARGET_PROPERTY_WITH_DEFAULT(_target_static_lib ${_target} STATIC_LIB "")
   GET_TARGET_PROPERTY_WITH_DEFAULT(_target_dependency_libs ${_target} LT_DEPENDENCY_LIBS "")
   GET_TARGET_PROPERTY_WITH_DEFAULT(_target_current ${_target} LT_VERSION_CURRENT 0)
   GET_TARGET_PROPERTY_WITH_DEFAULT(_target_age ${_target} LT_VERSION_AGE 0)
   GET_TARGET_PROPERTY_WITH_DEFAULT(_target_revision ${_target} LT_VERSION_REVISION 0)
   GET_TARGET_PROPERTY_WITH_DEFAULT(_target_installed ${_target} LT_INSTALLED yes)
   GET_TARGET_PROPERTY_WITH_DEFAULT(_target_shouldnotlink ${_target} LT_SHOULDNOTLINK yes)
   GET_TARGET_PROPERTY_WITH_DEFAULT(_target_dlopen ${_target} LT_DLOPEN "")
   GET_TARGET_PROPERTY_WITH_DEFAULT(_target_dlpreopen ${_target} LT_DLPREOPEN "")
   GET_FILENAME_COMPONENT(_laname ${_target_location} NAME_WE)
   GET_FILENAME_COMPONENT(_soname ${_target_location} NAME)
   SET(_laname ${PROJECT_BINARY_DIR}/${_laname}.la)
   FILE(WRITE ${_laname} "# ${_laname} - a libtool library file\n")
   FILE(WRITE ${_laname} "# Generated by CMake ${CMAKE_VERSION} (like GNU libtool)\n")
   FILE(WRITE ${_laname} "\n# Please DO NOT delete this file!\n# It is necessary for linking the library with libtool.\n\n" )
   FILE(APPEND ${_laname} "# The name that we can dlopen(3).\n")
   FILE(APPEND ${_laname} "dlname='${_soname}'\n\n")
   FILE(APPEND ${_laname} "# Names of this library.\n")
   FILE(APPEND ${_laname} "library_names='${_soname}.${_target_current}.${_target_age}.${_target_revision} ${_soname}.${_target_current} ${_soname}'\n\n")
   FILE(APPEND ${_laname} "# The name of the static archive.\n")
   FILE(APPEND ${_laname} "old_library='${_target_static_lib}'\n\n")
   FILE(APPEND ${_laname} "# Libraries that this one depends upon.\n")
   FILE(APPEND ${_laname} "dependency_libs='${_target_dependency_libs}'\n\n")
   FILE(APPEND ${_laname} "# Names of additional weak libraries provided by this library\n")
   FILE(APPEND ${_laname} "weak_library_names=''\n\n")
   FILE(APPEND ${_laname} "# Version information for ${_laname}.\n")
   FILE(APPEND ${_laname} "current=${_target_current}\n")
   FILE(APPEND ${_laname} "age=${_target_age}\n")
   FILE(APPEND ${_laname} "revision=${_target_revision}\n\n")
   FILE(APPEND ${_laname} "# Is this an already installed library?\n")
   FILE(APPEND ${_laname} "installed=${_target_installed}\n\n")
   FILE(APPEND ${_laname} "# Should we warn about portability when linking against -modules?\n")
   FILE(APPEND ${_laname} "shouldnotlink=${_target_shouldnotlink}\n\n")
   FILE(APPEND ${_laname} "# Files to dlopen/dlpreopen\n")
   FILE(APPEND ${_laname} "dlopen='${_target_dlopen}'\n")
   FILE(APPEND ${_laname} "dlpreopen='${_target_dlpreopen}'\n\n")
   FILE(APPEND ${_laname} "# Directory that this library needs to be installed in:\n")
   FILE(APPEND ${_laname} "libdir='${CMAKE_INSTALL_PREFIX}${_install_DIR}'\n")
   INSTALL( FILES ${_laname} DESTINATION ${CMAKE_INSTALL_PREFIX}${_install_DIR})
 ENDMACRO(CREATE_LIBTOOL_FILE)

不幸的是，这对我现在不起作用，因为最近版本的 cmake 不再支持 GET_TARGET_PROPERTY(... LOCATION)。我看到有一个可以使用的生成器表达式 ($) 代替它，但是可以使用生成器表达式的规则不同，我对 CMake 的经验仍然非常有限。

任何人都可以给我一些提示，让我知道我可以如何为 CMake 的最新版本调整上述宏，或者如果已经存在替代解决方案，可能会指出我吗？

编辑：此问题已关闭，因为它与此“相同”：How can I remove the "the Location property may not be read from target" error in CMake?

内容相似，但不一样。上面链接的问题解释了如何替换特定的代码行，而我的问题是寻求有关如何为此处找到的代码提出替代解决方案的指导：https://gitlab.kitware.com/cmake/community/-/wikis/contrib/macros/LibtoolFile
