Auto-downloaded C Driver incorrectly inherits BUILD_VERSION

      Users may want to be notified that the auto-downloaded C Driver, when built and installed alongside the C++ Driver, may be configured with an incorrect API version number (BUILD_VERSION) due to incorrectly inheriting the value from the C++ Driver's CMake configuration cache. The C Driver's reported API version (both in libraries and packages) may be incorrectly set to either 0.0.0 or set to the same value as the C++ Driver's API version number.

      This primarily affects C++ Driver 3.11 and 4.0. This only affects the C Driver that is auto-downloaded when CMake does not find an existing installation via find_package() or if the user uses add_subdirectory() to import C Driver CMake targets in their own higher-level CMake project.

      Note: although the bug is technically present with C++ Driver 3.9 and 3.10, the auto-download C Driver in those releases use version 1.25, which temporarily disabled support for BUILD_VERSION, and is therefore not susceptible to this configuration bug.

      C++ Driver 3.9.0 added support for "auto-downloading" the C Driver in CXX-2695. However, the auto-downloaded C Driver may incorrectly inherit the BUILD_VERSION of the C++ Driver when the variable is set during configuration. This results in the C Driver libraries having an API version number that is the same as the C++ Driver libraries or set to 0.0.0 (the default value when not explicitly set). The incorrect API version number is propagated to the C Driver libraries and package files when they are installed alongside the C++ Driver.
