I recently incorporated spout2 into a project and our package manager of choice is VCPKG. There were some components missing from the build pipeline to make this work out of the box, namely the CMakeLists.txt you provide does not support installing and there were a few issues with building outside of visual studio.
I’ve made everything work for us now using the patching system to apply patches to your source before building it, however it strikes me that this might be of interest to other developers as well so I’m asking if this is something you would like me to make a bit more general and create pull requests for?
The changes that I foresee would be isolated to the CMake build pipeline and specifically involve creating install targets and possibly isolating some file-copying to “Visual Studio Only”. Install targets are of benefit for general development as well and is not isolated to VCPKG package-management.
