Master won't build on windows

[sbrkopac]

Describe the bug
Looks like 7a4a0a0 broke installation of VSG on windows. Looks like when VSG_MACROS_INSTALLED is enabled then the uninstall.cmake file is skipped from the installation.

Expected behavior
VSG should install correctly to the target folders.

@rhabacker Could you please take a look as well.

Before merging pr #313 builds were performed on Windows with MSVC, see e.g. https://github.com/vsg-dev/VulkanSceneGraph/runs/3524834865, which should have raised such issues.
Unfortunately, they do not perform a "make install" step that should be added to the corresponding CI configuration.

Looks like when VSG_MACROS_INSTALLED is enabled then the uninstall.cmake file is skipped from the installation.

When vsgMacros.cmake is included from the top level CMakeLists.txt of the VulkanSceneGraph git repo, VSG_MACROS_INSTALLED is not set and the file uninstall.cmake is installed along with vsgMacros.cmake.

When vsgMacros.cmake is included from vsgConfig.cmake as a result of a call to find_package(vsg) in a package depending on vsg, VSG_MACROS_INSTALLED is set and uninstall.cmake must not be installed, only used.

This is known to work on linux builds, see https://build.opensuse.org/package/show/home:rhabacker:branches:games/libvsg

Installing that file also works with mingw builds

The only possibility I see is that -DVSG_MACROS_INSTALLED=1 has been added to the cmake command line for VulkanSceneGraph.

[sbrkopac]

Adding the -DVSG_MACROS_INSTALLED=1 to my build produces the same error. It doesn't look my uninstall.cmake is being produced at all.

[sbrkopac]

So it looks like what happened was I manually cleaned my build directory which is where some of the templates are sitting. When I do that - they obviously can't be found. I've created a draft pull request to put them in a more appropriate location which should prevent this from happening in the future.

Snuck in a quick change to also address #319
