# Defines a few environment variables that simplify cross-platform (Linux/OSX) build scripts for conda packages.

# This variable can be used to (indirectly) read/set the contents of either
# LD_LIBRARY_PATH or DYLD_LIBRARY_PATH, depending on your platform.
# To set as a prefix of a command (e.g. before 'make check'), use eval:
#  eval $LIBRARY_SEARCH_VAR=/path/to/lib;/another/path/to/lib make check
# To read (using modern bash indirection syntax):
#  echo ${!LIBRARY_SEACH_VAR}
