CMake: how to determine all the .DLL/.SO files that are need for an executable?

Question

Let\'s assume my program needs several DLL\'s to work. I should provide that DLLs to the user in my distribution. For now I need QtCore4.DLL, QtGui4.DLL, msvcp90.DLL, msvcr9

Answer 1

As suggested by Andre there is InstallRequiredSystemLibraries for finding/installing the correct C/C++ runtime. There is also BundleUtilities that can be used to find the other dependencies of your application, library and/or plugins.

It can never pick things up like runtime loaded plugins, but you can add them along with the library directories that should be used. In the most recent versions of CMake quite a few improvements have been made to make BundleUtilities more reliable on all platforms.

Answer 2

You can use Dependency Walker on windows (or the cmd-line dumpbin tool from visual studio). However this is not really a CMake solution and there is not really standard solution with Cmake.

There is, however, the InstallRequiredSystemLibraries module, which you can use to get the system dlls (msvc[r|p]90.dll with msvc and mingw10.dll with mingw).
