This was the problem, this Matlab Mexfile has dependencies to a shared
library generated in another subdirectory of the build system.
I replace the line
TARGET bookread_exp_matlab
with
OUTPUT
${MPTK_BINARY_DIR}/src/matlab/experimental/bookread_exp.${MEX_EXTENSION}
POST_BUILD
In order to ensure that the shared library is build before the Mexfile,
and it work fine.
Thanks.

It was working fine till version 2.6.0. But now I ve got a make error:
make[2]: *** No rule to make target `src/matlab/bookread.mexglx', needed
by `src/matlab/CMakeFiles/bookread_matlab'. Stop.
make[1]: *** [src/matlab/CMakeFiles/bookread_matlab.dir/all] Error 2
make: *** [all] Error 2
Did i miss something basic ? And why such differences in make files
generated by CMake 2.6.0 and CMake 2.4.8 ?
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.
