how to mex on mesh_boolean

[Polofes]

I have build and compiled the library with CMAKE and Visual studio 17. But I can not mex the mesh_boolean in MATLAB. mex is asking for the addresses of different libraries which I provide by -I option but after some steps it is asking for a config.h file that I do not have.

There are different mesh_boolean.cpp files and I am using the one that is in the gptoolbox/mex folder.

this is the message:

How can I fix this?!

[alecjacobson]

libigl is supposed to be grabbing cgal for you. Are you able to successfully build libigl (outside of gptoolbox)?

[Polofes]

I have downloaded CGAL and Libigl as header only and seperately outside gptoolbox, but when mex is built another libigle is inside gptoolbox.

Now I built the libigl outside gptoolbox with CGAL, using CMAKE and VS19 and it was successful as in here:

103>------ Build started: Project: ALL_BUILD, Configuration: Debug x64 ------
103>Building Custom Rule C:/Majid/SSM/Code/Matlab Code/libigl/CMakeLists.txt
========== Build: 103 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

Still mex is giving me the same issue.

I have also Blas, Boost, Eigen, and Lapack independently before building gptoolbox. Should I get rid of everything and let CMAKE download them while building the gptoolbox?

[Polofes]

@alecjacobson any hint for me? I am stuck here. any general hint is also of great help.
