Hi @jchristopherson,

I have updated the README based on the workflow you provided. Could you please review it to ensure the CMake instructions are accurate?

Thank you,
Ali

Hi @gha3mi

It can actually be much simpler. For a typical use case the default build is a Release build and fully optimized. A simple series of calls such as the following will suffice.

cd build
cmake ../build
make

This will configure and build. If tests are desired, then add -DBUILD_TESTING to the configuration step as follows.
cmake ../build -DBUILD_TESTING=TRUE

And then a simple call to make will suffice, as before.

Thank you!
