I am working off of a cluster and since I do not have sudo privileges there, I had to install a toolkit at a different path
export PATH = ~/bin/tool_kit/bin:$PATH
bin is the only location you definitely need to do anything with:
# using end of the PATH, unless you know you want to override like-named system binaries PATH=$PATH:$HOME/bin/tool_kit/bin
export is needed here, as the
PATH variable is already in the environment.
If and only if your software didn't compile in a
rpath pointing to the anticipated runtime library locations, you may also wish to set an LD_LIBRARY_PATH:
include files are used only when compiling other software, and are not generally needed at runtime.
