```
hugin-2019.2.0/src/foreign/levmar/misc_core.c:45:#define GEMM LM_MK_BLAS_NAME(gemm)
```

This function is a BLAS function:
https://en.wikipedia.org/wiki/Basic_Linear_Algebra_Subprograms#Level_3

Thus, since levmar is built as a static library, Hugin itself should
call `find_package(BLAS)` and `huginbase` should link against
`BLAS_LIBRARIES`.

Attached patch fixes this (in an admittedly slightly crude way) for me.

Title:
  levmar uses BLAS when built with LAPACK, but Hugin does not link
  against BLAS

Status in hugin package in Gentoo Linux:
