# CMake file for Matlab/Octave support
|
|
#
|
|
# Matlab code generation and compilation is broken down into two distinct
|
|
# stages: configure time and build time. The idea is that we want to give
|
|
# the user reasonable guarantees that once they type 'make', wrapper
|
|
# generation is unlikely to fail. Therefore we run a series of tests at
|
|
# configure time to check the working status of the core components.
|
|
#
|
|
# Configure Time
|
|
# During configure time, the script attempts to ascertain whether the
|
|
# generator and mex compiler are working for a given architecture.
|
|
# Currently this involves:
|
|
# 1) Generating a simple CV_EXPORTS_W symbol and checking whether a file
|
|
# of the symbol name is generated
|
|
# 2) Compiling a simple mex gateway to check that Bridge.hpp and mex.h
|
|
# can be found, and that a file with the mexext is produced
|
|
#
|
|
# Build Time
|
|
# If the configure time tests pass, then we assume Matlab wrapper generation
|
|
# will not fail during build time. We simply glob all of the symbols in
|
|
# the OpenCV module headers, generate intermediate .cpp files, then compile
|
|
# them with mex.
|
|
# ----------------------------------------------------------------------------
|

|
|
# PREPEND
|
|
# Given a list of strings IN and a TOKEN, prepend the token to each string
|
|
# and append to OUT. This is used for passing command line "-I", "-L" and "-l"
|
|
# arguments to mex. e.g.
|
|
# prepend("-I" OUT /path/to/include/dir) --> -I/path/to/include/dir
