决定在我的构建中尝试使用LTO（CentOS 7，CMake 3.14.3，gcc 8.2.1，-std=c++17）：
# this adds "-flto -fno-fat-lto-objects"
set(CMAKE_INTERPROCEDURAL_OPTIMIZATION TRUE)
除以下项目外，所有项目均可正常运行

由于vcpkg提供的一些神秘原因libazurestorage.a（在没有 LTO的情况下构建）无法解析std::basic_string<char, std::char_traits<char>, std::allocator<char> >::~basic_string()（并且只有该符号！）。
要使其变得更加有趣-使用libazurestorage.a的其他项目也可以正常构建。我已经检查了链接器的cmdline，它们看起来几乎是相同的（几乎相同的一组lib，几乎相同的顺序）。
任何想法可能有什么问题吗？还是如何弄清楚为什么其他项目可以正常构建？
