Hello, so following a tutorial on how to build the library myself for Visual Studio 2022 on Windows 10, everything so far has gone to plan apart from the final stage whilst using cmake…
All files have been transfered to the build folder via cmake, only Iam missing 3 files from which to build in Visual Studio, namley these files…
These files are from the tutorial…
Any help on where Iam going wrong would be helpful… I have a wedding to attend at the end of the year! Been trying for 3 days already! lol… Cheers in addvance… ‘’ }

This is what my build folder looks like, those 3 files are missing?

Hi, thanks for a speedy reply, you mean the text from the config box in cmake?

_Visual Studio_ usage question…
the error is non-specific. it might refer to that executable, or to a dll required by this executable.
if the exe isn’t there, it may be missing because the build (of the application) failed.
if the exe is _elsewhere_, VS should have looked there instead.
if the exe is there, this could mean a required dll is missing. then you need to mess around with the PATH environment variable. getting a changed environment variable to have an effect can require logging out of your windows session and logging in again (not just locking the session).
