[CMake] Possible differences in result of list(SORT)

[Nils Gladitz]

list(SORT) does an std::sort() of std::strings.
I think CMake does not perform any character set conversions so the 
available strings retain the encoding as used in the input file and 
std::string ordering is based on byte-wise comparison.
