code execution cannot proceed because cpprest_2_10.dll was not found

Question

My aim is to use the Rest API in Visual Studio. I downloaded the C++ tool vcpkg from https://github.com/Microsoft/vcpkg and followed the instructions on https://github.com/Microsoft/cpprestsdk to install cpprestsdk. That worked fine.

Then, in Visual Studio in the properties of the solution explorer, I included the following paths from the vcpkg folder into "VCC++ Directories->Include directories":

vcpkg-master\vcpkg-master\buildtrees\cpprestsdk\src\v2.10.2-718a4e55e9\Release\include\cpprest

vcpkg-master\vcpkg-master\buildtrees\cpprestsdk\src\v2.10.2-718a4e55e9\Release\include

vcpkg-master\vcpkg-master\buildtrees\cpprestsdk\src\v2.10.2-718a4e55e9\Release\include\pplx

Then I run my code and the following errors occur:

LNK2001 unresolved external symbols (32 errors like this)

I googled it and was told to include the respective ".lib"-files into "Properties->Linker->Input->Additional Dependencies" and to include the paths of the corresponding ".dll"-files into "Properties->Linker->General->Additional Library Directories", what I did.

Now, running the code again, just the following error occurs:

code execution cannot proceed because cpprest_2_10.dll was not found. Reinstalling the program may fix the problem,

although the "cpprest_2_10.dll" is in the path, which I included previously.

I have no idea what the problem is. Thank you in advance for your time.

Try to put the missing dll file right to the directory of your compiled exe.

Or check this answer to set a path so your binary can find the dll file:
