Do your other projects use CMake to generate the solution files? If so, then
"Rebuild Solution" should re-run CMake. The only thing that should prevent
it is if somebody sets "CMAKE_SUPPRESS_REGENERATION" in their CMakeLists.txt
file. Maybe the other projects do that...? (But if they do, then changing a
CMakeLists.txt file means you have to manually re-run CMake...)

HTH,
David
