FYI I get a “CATASTROPHIC” error popup if I accidentally run “Install All Targets” while in the middle of a build in a local CMake project using VGDB 5.4.100.2765. There are no ill effects, no crash, and once I dismiss the message everything works as normal.
Thanks for reporting this. The message is just the default text for the default E_FAIL code returned by Visual Studio when trying to start another build before the current build completes (target installation counts as a special build). It should indeed not have any consequences and we will consider replacing it with something more informative next time we redesign that part.
