FindMatlab 2018a API

Cris Luengorequested to merge
crisluengo/cmake:FindMatlab-2018a-API into master

This MR allows FindMatlab to work with MATLAB R2018a and newer, addressing issues raised in #18419 (closed).

It contains work by @seanwarren in !2442 (closed) (superseding that MR, Sean has said not to have time to complete it), and some further modifications.

  • MX_LIBRARY is always linked to, it is no longer necessary to give this parameter (it will silently be ignored).

  • Two new options, R2017b and R2018a, can be given. These options mimic the options that the mex command gained in MATLAB R2018a. The first one (it is the default) selects the "compatibility mode", allowing older MEX-files to be compiled with the newer MATLAB. The second option is the alternative, enabling the new complex-interleaved API in R2018a and newer. If FindMatlab uses an older version of MATLAB, these options are ignored.

  • We follow the guidance given by a MathWorks employee, and try to mimic the compile and link commands as issued by the mex command.
