C Driver build error (v1.21.0)

Working with Data Drivers
1

Hello, I am trying to build the C Driver for MongoDB version 1.21.1 and I am getting an error.
I’m building this driver in Docker with Ubuntu 16.04, CMake 3.17, and GNU 5.4.0.
My building commands:

mkdir -p /deps \
    && cd /deps \
    && apt-get install -y libsasl2-dev wget \
    && LATEST_RELEASE="https://api.github.com/repos/mongodb/mongo-c-driver/releases/latest" \
    && TAG=$(curl --silent $LATEST_RELEASE | grep -Po '"tag_name": "\K.*(?=")') \
    && wget "https://github.com/mongodb/mongo-c-driver/releases/download/$TAG/mongo-c-driver-$TAG.tar.gz" \
    && tar xzf "mongo-c-driver-$TAG.tar.gz" \
    && cd "mongo-c-driver-$TAG" \
    && mkdir cmake-build && cd cmake-build \
    && cmake \
        -DCMAKE_BUILD_TYPE=Release \
        -DENABLE_ICU=OFF \
        -DOPENSSL_USE_STATIC_LIBS=TRUE \
        -DCMAKE_PREFIX_PATH="/opt/openssl" \
        -DENABLE_AUTOMATIC_INIT_AND_CLEANUP=OFF .. \
    && make -j$(nproc) install

And starting from the last release (I guess), I’m getting this error:

Any help would be appreciated!

Can you provide the output of the first part of the CMake command? Specifically, the line that begins -- Maintainer flags:.
