// Use CRYPTOPP_DATA_DIR last. The problem this sidesteps is, finding an
// old version of Crypto++ library in CRYPTOPP_DATA_DIR when the library
// has been staged in DESTDIR. Using CRYPTOPP_DATA_DIR first only works
// as expected when CRYPTOPP_DATA_DIR is empty before an install. We
// encountered this problem rather quickly during testing of Crypto++ 8.1
// when Crypto++ 8.0 was installed locally. It took some time to realize
// where the old test data was coming from.
