OPENCLAMDBLAS and OPENCLAMDFFT never detected under linux.
lib64/import and lib32/import is the path on Windows but not Linux.
for CLAMDBLAS library we should use CLAMDBLAS_PATH (not CLAMDFFT_PATH)

If we have perfect matches (min_dist == 0.0), then strict comparison
fails. Making it non-strict results in treating perfect matches as
good.

weights array is only allocated for (l_count+1) elements,
but then weights[l_count+1] element is accessed.
