# Locate an Netlib implementation.
# Pre-built binaries for windows can be found at http://icl.cs.utk.edu/lapack-for-windows/lapack/
#
# Defines the following variables:
#
# Netlib_FOUND - Found the OPENCL framework
#
# Also defines the library variables below as normal
# variables. These contain debug/optimized keywords when
# a debugging library is found.
#
# Netlib_LIBRARIES - libNetlib
#
# Accepts the following variables as input:
#
# Netlib_ROOT - (as a CMake or environment variable)
# The root directory of where Netlib libraries are found
#
# FIND_LIBRARY_USE_LIB64_PATHS - Global property that controls whether FindNetlib should search for
# 64bit or 32bit libs
#
# Netlib_COMPILERS - Prioritized list of compiler flavors that this find package should search for when
# looking for libraries. The user could have multiple flavors of Netlib installed
# and setting this before calling FindPackage will alter order searched
#-----------------------
# Example Usage:
#
# find_package(Netlib REQUIRED)
# include_directories(${Netlib_INCLUDE_DIRS})
#
# add_executable(foo foo.cc)
# target_link_libraries(foo ${Netlib_LIBRARIES})
#
