# TODO:
# - Introduce build step to $ISSM_DIR/jenkins/jenkins.sh to compile Fortran code in $ISSM_DIR/src/c/modules/GiaDefelectionCorex/ to C with f2c
#       - Then, revert $ISSM_DIR/externalpackages/emscripten/install.sh to r24306 and test clean build
#       - When builtin support for Fortran is available, remove build step
