I am building opencv, and it will automatically detect dependency, I noticed this
– Could not find OpenBLAS include. Turning OpenBLAS_FOUND off
– Could not find OpenBLAS lib. Turning OpenBLAS_FOUND off
It looks like no matter it can find OpenBLAS or not, it always can be built, how do I know if this dependency will be used or not?
For example, I am benchmarking performance of dnn using opencv_perf_dnn
