# The matrix can be configured with environment variables MATRIX_CC,
# MATRIX_CMAKE and MATRIX_REMOTE (default: MATRIX_CC='gcc clang',
# MATRIX_CMAKE='no yes', MATRIX_REMOTE='no yes').
# It calls the build.sh script which runs one build with setup environment
# variables : CC, CMAKE and REMOTE (default: CC=gcc, CMAKE=no, REMOTE=no).
