# ----- 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_DIR Path to "mex.h"
|
||||
# MATLAB_LIBRARY_DIR 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' ..
