I installed GCC into a conda environment:
conda create -n gccenv gcc_linux-64=8.4.0 gxx_linux-64=8.4.0
When I set LIBRARY_PATH, it is only picked up by the system GCC however:
conda activate gccenv
export LIBRARY_PATH=/foo/bar
/usr/bin/g++ --print-search-dirs | tr ':' $'\n'
OUTPUT: libraries
=/foo/bar/x86_64-linux-gnu/9/

When I try to compile an open source project with the conda GCC, it fails to find a library in the /foo/bar directory and exits with a linker error. How can I get the conda GCC (which is the exact version I need of GCC) to listen to LIBRARY_PATH?
