    If you are seeing a compilation error please try the following steps to
    successfully install cmake:
    1) Upgrade to the latest pip and try again. This will fix errors for most
       users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
    2) If on Linux, with glibc < 2.12, you can set PIP_ONLY_BINARY=cmake in
       order to retrieve the last manylinux1 compatible wheel.
    3) If on Linux, with glibc < 2.12, you can cap "cmake<3.23" in your
       requirements in order to retrieve the last manylinux1 compatible wheel.
    4) Open an issue with the debug information that follows at
