I have a resource constrained lab machine (thats not controlled by me), which basically only allows me to write to an external hdd.
I need to compile my class project using boost and pcl. My procedure has been to create a conda environment inside the external hdd, and then conda install -c conda-forge boost pcl.
This works as far as getting the packages installed. When I need to compile, I use the following CMake toolchain file:
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)
This gets the compiling job done when running cmake and make. The problem begins when you try to link; I get:
/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)

My understanding is that pcl's boost dependency is not being correctly resolved during link time. Is there any way I can help CMake resolve this?
