问题是，在构建项目时，cmake 没有找到 boost-graph 库。但是，这个库已安装在系统上。
大家好！我遇到过这样的问题。我尝试构建一些依赖于 Boost 和 CLapack 包的项目。（我之前已经安装了这些包）我使用了这个命令：
$ cmake ../project_name/ -DCLAPACK_BASE_DIRECTORY=/home/vitalii/clapack-3.2.1-CMAKE -DCLAPACK_BUILD_DIRECTORY=/home/vitalii/clapack-3.2.1-CMAKE/BUILD
终端的输出是：

CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Boost-1.74.0/BoostConfig.cmake:141 (find_package):
Found package configuration file:
/usr/lib/x86_64-linux-gnu/cmake/boost_graph-1.74.0/boost_graph-config.cmake
but it set boost_graph_FOUND to FALSE so package "boost_graph" is
considered to be NOT FOUND. Reason given by package:
No suitable build variant has been found.
The following variants have been tried and rejected:

/usr/share/cmake-3.22/Modules/FindBoost.cmake 的 587-594 行是：

/usr/lib/x86_64-linux-gnu/cmake/Boost-1.74.0/BoostConfig.cmake 的 238-262 行是：

该命令证明boost_graph库存在于我的系统中：

我也阅读了一些相关问题的答案。我尝试 cmake 使用选项 -DBoost_DEBUG=TRUE 来获取更多信息，因为这些答案中的一些用户推荐了它：

不幸的是，我还不知道如何解决这个问题。你有什么建议吗？
