instrumentation-interrupt

• The cmake-instrumentation(7) data version has been updated to 1.2.

• cmake-instrumentation(7) API now records an overall cmakeBuild snippet even when a cmake --build invocation is interrupted by the user (for example with Ctrl+C). The snippet includes a new interruptSignal field, recording the signal that interrupted the build, so that consumers can distinguish an interrupted build from one that ran to completion.

• Similarly, cmake-instrumentation(7) API now records an overall cmakeInstall snippet, marked with the same interruptSignal field, when a cmake --install invocation is interrupted by the user.

• Similarly, cmake-instrumentation(7) API now records an overall ctest snippet, marked with the same interruptSignal field, when a ctest(1) invocation is interrupted by the user. On interrupt CTest stops scheduling further tests and preserves its checkpoint file so that a later ctest -F can resume the interrupted test set.
