Question: ERROR [builder 41/48] RUN cmake3 -DCMAKE_PREFIX_PATH=/usr -DCMAKE_INSTALL_PREFIX=/usr -GNinja -S aws-nitro-enclaves-sdk-c -B aws-nitro-enclaves-sdk-c/

I am setting up a Security Enclaved instance in my machine. I created a Amazon Linux 2 AMI with c5.xlarge instance according to the document, officially provided. -> https://github.com/aws/aws-nitro-enclaves-sdk-c/blob/main/docs/kmstool.md

I tried every steps specified in the document. But when I run the docker build command,
docker build --target kmstool-instance -t kmstool-instance .,
It gives an error,

 => CACHED [builder 39/48] RUN mv aws-nitro-enclaves-nsm-api/target/release/nsm.h /usr/include                                                               0.0s

Please give me a way to solve this!!!

I can close this issue. I need to go inside the aws-nitro-enclaves-sdk-c directory and execute the docker command.
