# 'project.o' should be replaced with the make output for your project, and
# you may need to rename it if it isn't something emcc recognizes
# (for example, it might have a different suffix like 'project.so' or
# 'project.so.1', or no suffix like just 'project' for an executable).
# If the project output is a library, you may need to add your 'main.c' file
# here as well.
