# 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.
