Shouldn't this feedback go upstream (to CMake)?

Title:
  hugin fails to compile when using Intel's MKL as lapack lib

Status in Hugin - Panorama Tools GUI:
  Incomplete

Bug description:
  Hugin's FindLAPACK cmake module is too simplistic to properly work with Intel's MKL (Math Kernel Library -- a processor-tuned version of BLAS, CBLAS, and LAPACK).  cmake finds liblapack.so just fine in /usr/lib at configure time, but the MKL implementation of lapack actually needs to link to some additional libraries, which cmake doesn't pick up on if it's using the FindLAPACK module that's included in the 2009.4 source tree.  Please use the FindLAPACK module that's provided with cmake instead.
