[Question] How can I static link mkl or use mkl through vcpkg?

[wuchun]

I see that in the CMakeLists.txt here, we only do static linking for python. I'm wondering whether we can do static linking for C++ as well. I tried to just rm L191-L192 so that the code tries static linking even when NOT PYBIND, but was getting many compile errors, for example:

/usr/bin/ld: ../../src/libdiskann.a(math_utils.cpp.o): in function `math_utils::compute_vecs_l2sq(float*, float*, unsigned long, unsigned long) [clone ._omp_fn.0]':
math_utils.cpp:(.text+0xca): undefined reference to `cblas_snrm2'

Are there other archive files that need to be specified or is the issue something else?

I also have another project that already installs mkl through vcpkg. I followed their usage doc and added L3-L4 from that to diskann's CMakeLists.txt. The whole project compiles fine but get runtime error for undefined symbol: mkl_trans_mkl_somatcopy or undefined symbol: mkl_lapack_slange.

Any help is really appreciated.
