# Find MKL library

# MKL_FOUND - set to true if MKL is found

# MKL_INCLUDE_DIR - Directories containing the MKL header files

# MKL_DEFINITIONS - Compilation options to use MKL

# MKL_LIBRARIES - List of libraries to link against MKL interface.
|

# May be null if the compiler supports auto-link (e.g. VC++).
|

# MKL_USE_FILE - The name of the cmake module to include to compile
|

|
# applications or libraries using MKL.
