# Try to find TREXIO library;
# If found, it will define the following variables (note the plural form):
# TREXIO_FOUND - System has libtrexio;
# TREXIO_INCLUDE_DIRS - The TREXIO include directories;
# TREXIO_LIBRARIES - The libraries needed to use TREXIO;
# If TREXIO has been installed in a non-standard location, one can set an
# environment variable $TREXIO_DIR in the current shell:
# $ export TREXIO_DIR=<custom_path>
# to indicate the prefix used during the TREXIO installation
# (typically `./configure prefix=<custom_path> ..` or `cmake -DCMAKE_INSTALL_DIR=<custom_path> ..`)
# This file should be located WITHIN your project source tree. # This file should be located WITHIN your project source tree.
