# ----- 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' .. |

# Matlab tends to use some non-standard prefixes and suffixes on its libraries. |
|
# 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. |
|
# |
|
# This function modifies the library prefixes and suffixes used by |
|
# find_library when finding Matlab libraries. It does not affect scopes |
|
# outside of this file. |
