# FindBLAS

Find BLAS library

This module finds an installed fortran library that implements the BLAS linear-algebra interface (see http://www.netlib.org/blas/). The list of libraries searched for is taken from 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)
  - 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 or CXX must be enabled to use Intel MKL

For example, to use Intel MKL libraries and/or Intel compiler:

    set(BLA_VENDOR Intel10_64lp)
    find_package(BLAS)
