Issue #294: "apple silicon build problem(s?)": If the "--flavor/-f" flag is not specified on the command line, then complain loudly, print help and exit. The script used to default to "Unix Makefiles". Updates: - Add missing "-DHAVE_LIBPNG" compiler command line define when the PNG library is detected/present for screen capture support. - Add "clang64" to the list of MinGW64 platforms for which the .travis/deps.sh script can install build dependencies. - Add PThread4W_FOUND to the condition that sets async I/O for Win32 when using vcpkg for build dependencies. - Add vs2022-x64, vs2019-x64 and vs2017-x64 build environments to build 64-bit Windows executables. - Use simulator AIO only where needed by the simulator (i.e., the simulator calls/uses AIO_CHECK_EVENT in sim_instr()) - Add "USES_AIO" flag to add_simulator() to mark a simulator that acutally uses asynchronous I/O. - Build "_aio" SIMH core library variants that have AIO turned on, link with the "_aio" variant when a simulator sets USES_AIO. - Emit a warning message when WITH_ASYNC is False (CMake configuration option) to notify the user/developer that some functionality will be crippled. Affected simulator builds: 3b2 family, PDP-6, PDP-11, VAX family, IMLAC and TT2500. The makefile and cmake/generate.py also updated to remain in sync with CMake. N.B.: Simulators still link with the underlying platform's threading library. SEL32 requires pthreads or equivalent threading library, independent of AIO. - cmake/cmake-builder.sh - New "--no-aio" flag: Build simulators without async I/O. - New "--no-aio-intrinsics" flag: Don't build async I/O using compiler compare-exchange, atomic load intrinsics. - cmake/cmake-builder.ps1 - New "-noaio" flag: Build simulators without async I/O. - New "-noaiointrinsics" flag: Don't build async I/O using compiler compare-exchange, atomic load intrinsics. CMake 3.28.1 INTERFACE_LINK_LIBRARIES behavior change: The file name must now be an absolute path. Relative paths no longer accepted. Internally, SIMH enforces this if CMAKE_VERSION >= 3.19, when REAL_PATH was first implemented.
