| # ----- 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_BIN: The main Matlab "executable" (shell script) |
| # 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_LIBRARIES: 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 **usually** |
| # the MEXEXT with the preceding "mex" removed, |
| # though it's different for linux distros. |
| # |
| # 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' .. |

| # For example, libmx.dll on Windows (Windows does not add prefixes) and |
| # mkl.dylib on OS X (OS X uses "lib" prefixes). |
| # On some versions of Windows the .dll suffix also appears to not be checked. |
| # |

| # find_library when finding Matlab libraries. It does not affect scopes |
