【问题描述】:
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,然后是conda install -c conda-forge boost pcl。
就安装软件包而言,这是可行的。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)
这可以在运行 cmake 和 make 时完成编译工作。当您尝试链接时,问题就开始了;我明白了:
/usr/bin/ld: warning: libboost_system.so.1.66.0, needed by /media/libre/jbayardo/conda/envs/thesis-env/lib/libpcl_common.so, not found (try using -rpath or -rpath-link)

我的理解是 pcl 的 boost 依赖在链接期间没有得到正确解决。有什么办法可以帮助 CMake 解决这个问题?
