commit c892795ea3601a6d210a325b2ac566b1c30d3334
Author: Ruslan Baratov <address@hidden>
AuthorDate: Tue Jul 10 12:54:34 2018 +0300

    CMake: Respect BUILD_SHARED_LIBS
    
    Use standard CMake variable BUILD_SHARED_LIBS instead of introducing
    custom option CURL_STATICLIB.
    
    Use '-DBUILD_SHARED_LIBS=%SHARED%' in appveyor.yml.
    
    Reviewed-by: Sergei Nikulov
    Closes #2755
