This is a CMake find-module, which attempts to find c-ares without
a CMake package file being available. If such a file is available,
it uses that. Otherwise, it searches for the library and include
directory manually.
Remove some spaces at the end of lines. Change how variables are
referenced inside if() statements. Remove the space between if/endif
and the first parenthesis. Remove the duplicated condition from endif()
blocks. Make indentation more consistent. Remove unneeded duplicate
PRIVATE keywords from target_include_directories(). Remove redundant
set_source_files_properties() call, as the file is already GENERATED.
