# This script executes the matrix loops, exclude tests and cleaning.

# (default: BUILD_LIBPCAP=no, REMOTE=no, CC=gcc, CMAKE=no, CRYPTO=no, SMB=no).
# The matrix can be configured with environment variables
# MATRIX_BUILD_LIBPCAP, MATRIX_REMOTE, MATRIX_CC, MATRIX_CMAKE, MATRIX_CRYPTO
# and MATRIX_SMB
# (default: MATRIX_BUILD_LIBPCAP='no yes', MATRIX_REMOTE='no yes',
# MATRIX_CC='gcc clang', MATRIX_CMAKE='no yes', MATRIX_CRYPTO='no yes',
# MATRIX_SMB='no yes').
