# ----- Find Matlab/Octave ----- |
||||
# |
||||
# OpenCVFindMatlab.cmake attempts to locate the install path of Matlab in order |
||||
# to extract the mex headers, libraries and shell scripts. If found |
||||
# successfully, the following variables will be defined |
||||
# |
||||
# MATLAB_FOUND: true/false |
||||
# MATLAB_ROOT_DIR: Root of Matlab installation |
||||
# MATLAB_MEX_SCRIPT The mex script used to compile mex files |
||||
# MATLAB_INCLUDE_DIRS Path to "mex.h" |
||||
# MATLAB_LIBRARY_DIRS Path to mex and matrix libraries |
||||
# MATLAB_LIBS The Matlab libs, usually mx, mex, mat |
||||
# MATLAB_MEXEXT The mex library extension. It will be one of: |
||||
# mexwin32, mexwin64, mexglx, mexa64, mexmac, |
||||
# mexmaci, mexmaci64, mexsol, mexs64 |
||||
# MATLAB_ARCH The installation architecture. It is simply |
||||
# the MEXEXT with the preceding "mex" removed |
||||
# |
||||
# There doesn't appear to be an elegant way to detect all versions of Matlab |
||||
# across different platforms. If you know the matlab path and want to avoid |
||||
# the search, you can define the path to the Matlab root when invoking cmake: |

# |

# cmake -DMATLAB_ROOT_DIR='/PATH/TO/ROOT_DIR' .. |
