cmake: move Matlab scripts to opencv_contrib (#12541)
* matlab: move to opencv_contrib * cmake: preserve variables scope for processing modules - use macro instead of function to avoid scope resetspull/12581/head

# ----- 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' .. |

# ----- set_library_presuffix ----- |

||||
# 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. |
