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'.

FindBLAS
--------
Find Basic Linear Algebra Subprograms (BLAS) library
This module finds an installed Fortran library that implements the
BLAS linear-algebra interface (see http://www.netlib.org/blas/).
The approach follows that taken for the ``autoconf`` macro file,
``acx_blas.m4`` (distributed at
http://ac-archive.sourceforge.net/ac-archive/acx_blas.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:
* ``Goto``
* ``OpenBLAS``
* ``FLAME``
* ``ATLAS PhiPACK``
* ``CXML``
* ``DXML``
* ``SunPerf``
* ``SCSL``
* ``SGIMATH``
* ``IBMESSL``
* ``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``
* ``ACML_MP``
* ``ACML_GPU``
* ``Apple``
* ``NAS``
* ``Generic``
``BLA_F95``
if ``ON`` tries to find the BLAS95 interfaces
``BLA_PREFER_PKGCONFIG``
if set ``pkg-config`` will be used to search for a BLAS library first
and if one is found that is preferred
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``BLAS_FOUND``
library implementing the BLAS interface is found
``BLAS_LINKER_FLAGS``
uncached list of required linker flags (excluding ``-l`` and ``-L``).
``BLAS_LIBRARIES``
uncached list of libraries (using full path name) to link against
to use BLAS (may be empty if compiler implicitly links BLAS)
``BLAS95_LIBRARIES``
uncached list of libraries (using full path name) to link against
to use BLAS95 interface
``BLAS95_FOUND``
library implementing the BLAS95 interface is found
.. note::
C, CXX or Fortran must be enabled to detect a BLAS 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(BLAS)
Hints
^^^^^
Set the ``MKLROOT`` environment variable to a directory that contains an MKL
installation, or add the directory to the dynamic library loader environment
variable for your platform (``LIB``, ``DYLD_LIBRARY_PATH`` or
``LD_LIBRARY_PATH``).
