The idea of `check_library_exists_concat()` is that it detects an optional component and adds it to the list of libs that we also use in subsequent component checks. This caused problems when detecting components with unnecessary dependencies that were not yet built. CMake offers the `CMAKE_REQUIRED_LIBRARIES` variable to set libs used for component checks, which we already use in most cases. That left 4 uses of `check_library_exists_concat()`. Only one of these actually needed the 'concat' feature (ldap/lber). Delete this function and replace it with standard `check_library_exists()` and manual management of our `CURL_LIBS` list we use when linking build targets. And special logic to handle the ldap/lber case. (We have a similar function for headers: `check_include_file_concat()`. It works, but problematic for performance reasons and because it hides the actual headers required in `check_symbol_exists()` calls.) Ref: #11537 #11558 Fixes #11285 Fixes #11648 Closes #12070
