Mario Emmenlauer 807a129f3c Find{BLAS,LAPACK}: Include parent of points directory in search 
This is required if MKLROOT points to the subdirectory .../mkl/ instead of
the root of an Intel MKL library installation. Only in this case the MKL
will be searched starting from the parent directory, to detect relevant
dependencies in parallel subdirectories, like 'compiler' and 'tbb'.

FindLAPACK
----------
Find Linear Algebra PACKage (LAPACK) library
This module finds an installed Fortran library that implements the
LAPACK linear-algebra interface (see http://www.netlib.org/lapack/).
The approach follows that taken for the ``autoconf`` macro file,
``acx_lapack.m4`` (distributed at
http://ac-archive.sourceforge.net/ac-archive/acx_lapack.html).
Input Variables
^^^^^^^^^^^^^^^
The following variables may be set to influence this module's behavior:
``BLA_STATIC``
if ``ON`` use static linkage
``BLA_VENDOR``
If set, checks only the specified vendor, if not set checks all the
possibilities. List of vendors valid in this module:
* ``OpenBLAS``
* ``FLAME``
* ``Intel10_32`` (intel mkl v10 32 bit)
* ``Intel10_64lp`` (intel mkl v10+ 64 bit, threaded code, lp64 model)
* ``Intel10_64lp_seq`` (intel mkl v10+ 64 bit, sequential code, lp64 model)
* ``Intel10_64ilp`` (intel mkl v10+ 64 bit, threaded code, ilp64 model)
* ``Intel10_64ilp_seq`` (intel mkl v10+ 64 bit, sequential code, ilp64 model)
* ``Intel10_64_dyn`` (intel mkl v10+ 64 bit, single dynamic library)
* ``Intel`` (obsolete versions of mkl 32 and 64 bit)
* ``ACML``
* ``Apple``
* ``NAS``
* ``Generic``
``BLA_F95``
if ``ON`` tries to find the BLAS95/LAPACK95 interfaces
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``LAPACK_FOUND``
library implementing the LAPACK interface is found
``LAPACK_LINKER_FLAGS``
uncached list of required linker flags (excluding ``-l`` and ``-L``).
``LAPACK_LIBRARIES``
uncached list of libraries (using full path name) to link against
to use LAPACK
``LAPACK95_LIBRARIES``
uncached list of libraries (using full path name) to link against
to use LAPACK95
``LAPACK95_FOUND``
library implementing the LAPACK95 interface is found
.. note::
C, CXX or Fortran must be enabled to detect a BLAS/LAPACK library.
C or CXX must be enabled to use Intel Math Kernel Library (MKL).
For example, to use Intel MKL libraries and/or Intel compiler:
.. code-block:: cmake
set(BLA_VENDOR Intel10_64lp)
find_package(LAPACK)
