Building of executable and shared library with cmake, runtimelinker does not find dll

Question

I am working with gcc(cygwin), gnu make, windows 7 and cmake.

my cmake testprojekt has the following structure

rootdir
|-- App
|   |-- app.cpp
|   +-         


        

Answer 1

Your problem lies not with linker or compiler, but with the way Windows searches for DLL's.

The OS will use the following algorithm to locate the required DLL's:

Look in:

1. The directories listed in the Application-specific Path registry key;
2. The directory where the executable module for the current process is located;
3. The current directory;
4. The Windows system directory;
5. The Windows directory;
6. The directories listed in the PATH environment variable;

Thus you have two reasonable options if you don't want to clutter the OS directories with your app-specific dll:

1. Create an app-specific Path registry entry (I would go with this option);
2. Put your DLL in the same folder as your EXE;
3. Modify the PATH variable (but why would you do that, if you can go with option 1?);
