Linker error 2019 while compiling mex on matlab 2015b 64bit

Hi, I'm using Matlab2015b 64bit with compiler of Microsoft Visual C++ 2015. I'm trying to create a mex having a c interface funtction which calls a function myfunc_cpp inside, which is in the same folder:

void mexFunction(int nlhs, mxArray *plhs[], int nrhs, mxArray *prhs[]);

which is in the file mymexfilefunc.cpp. The matlab command I used:

   mex mymexfilefunc.cpp

I don't think I missed any libs. I got the following error:

Error using mex Creating library mymexfilefunc.lib and object mymexfilefunc.exp mymexfilefunc.obj : error LNK2019: unresolved external symbol "void __cdecl myfunc_cpp(...)" ...referenced in function "void __cdecl mexFunction(int,struct mxArray_tag * * const,int,struct mxArray_tag * * const)"... mymexfilefunc.mexw64 : fatal error LNK1120: 1 unresolved externals

I found a solution - compile the project in Release and add all the .obj that are created, which are used through the mexFunction to the command with their fullpath:

    mex pathobj1\obj1.obj pathobj2\obj2.obj mymexfilefunc.cpp
