    Building for older libraries

    VS2019 can build projects originally intended for earlier versions - so for example I could build a DLL which needed to link to VS2015 libraries - BUT...

    Does it literally build with VS2015 or does it still build with VS2019 but adjusting the memory management and name-mangling etc so that my own project will be able to link against the VS2015 libraries?

    VS2019 can build for VS2015, VS2017 & VS2019 - if the required build tools have been installed via VS Installer. AFAIK it builds for 2015/2017 as if the build had been done with those versions using that version of the CRT etc. Building for VS2015 should allow that project to link to VS2015 libraries - although I haven't tried it.
    All advice is offered in good faith only. All my code is tested (unless stated explicitly otherwise) with the latest version of Microsoft Visual Studio (using the supported features of the latest standard) and is offered as examples only - not as production quality. I cannot offer advice regarding any other c/c++ compiler/IDE or incompatibilities with VS.
