我有一台资源受限的实验室机器（不受我控制），它基本上只允许我写入外部硬盘。
我需要使用 boost 和 pcl 编译我的类项目。我的程序是在外部硬盘中创建一个 conda 环境，然后conda install -c conda-forge boost pcl。
这对于安装软件包来说已经足够了。当我需要编译时，我使用以下 CMake 工具链文件：
SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_SYSTEM_VERSION 1)
SET(CMAKE_C_COMPILER /XXX/bin/clang)
SET(CMAKE_CXX_COMPILER /XXX/bin/clang++)
SET(CMAKE_FIND_ROOT_PATH /YYY/conda/envs/thesis-env /XXX/llvm)
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
这样在运行 cmake 和 make 时就可以完成编译工作了。当您尝试链接时，问题就开始了；我得到：

我的理解是，pcl 的 boost 依赖项在链接时未得到正确解析。有什么方法可以帮助 CMake 解决这个问题吗？
