Compiling function with ROS custom messages inside

For my thesis I have developed a matlab function that uses the contents of custom packages ROS (.bag). Now I would need to compile my function to create an executable file (.exe). I used Matlab Compiler and everything works, generating the code, but when I launch the application I get the following message: "Can not find a MATLAB message class for type xxx.package / Sample. Error in filename.m line xx" Can someone help me? Do I have to add something to the compiler? Thank you.
