I can't even get the above example to work in 2.4. It looks like this
is a subdirectory of a larger build system. Can you reproduce this
problem in a self-contained example please?
If I replace the line
TARGET bookread_exp_matlab
with
OUTPUT
${MPTK_BINARY_DIR}/src/matlab/experimental/bookread_exp.${MEX_EXTENSION}
then it works in both 2.4 and 2.6.
