# Pointing to DLL Files in Visual CPP

When coding in Visual C++, we sometimes need to use some DLL libraries like FMOD, wxWidgets, Intel TBB etc. We download or build the library, setup directories to include and library files, finally #include <header.h>, #pragma comment(lib, "library.lib"), compile, run and...

Certainly our program also needs DLL file at runtime. Sure we have to attach it to the program when we distribute it, but do we really need to copy all these libraries to the Debug and Release subdirectories in our project? For a project run from Visual C++ to find required DLL files, they must be placed either in:

or in the PATH environmental variable. That's an option I've discovered yesterday. To use it in Visual C++, navigate to project properties / Configuration Properties / Debugging / Environment and set it to something like: PATH=$(PATH)$;C:\my_libraries\library_1\DLL_dir

If you do it correctly, your program launched from Visual C++ (with or without debugger - F5 or Ctrl+F5) will now be able to find required DLL libraries without need to copy them to your project directory.
