vcpkg

vcpkg on MinGW looks for Visual Studio

Following instructions at https://learn.microsoft.com/en-us/vcpkg/users/platforms/mingw

However, vcpkg requires Visual Studio to work. It seems that is related with vcpkg-cmake package.

$ ./vcpkg install zlib:x64-mingw-dynamic
Computing installation plan...
The following packages will be built and installed:
  * vcpkg-cmake[core]:x64-windows -> 2022-12-22
    zlib[core]:x64-mingw-dynamic -> 1.2.13
Additional packages (*) will be modified to complete this operation.
error: in triplet x64-windows: Unable to find a valid Visual Studio instance
Could not locate a complete Visual Studio instance
Solution

  • Looking at:

      * vcpkg-cmake[core]:x64-windows -> 2022-12-22
    zlib[core]:x64-mingw-dynamic -> 1.2.13

    shows that the host triplet is not set and the default is used.

    Try ./vcpkg install zlib --triplet x64-mingw-dynamic --host-triplet x64-mingw-dynamic instead or set the according environment variables VCPKG_DEFAULT_TRIPLET and VCPKG_DEFAULT_HOST_TRIPLET to change the default.
