Two updates suggested by Paul Koning:
- Enable building multiple simulator targets using a comma-separated list,
e.g.: pdp8,pdp11,3b2
- Unconditionally clean CMake's cache each time the script is invoked.
This eliminates confusing CMake configuration messages when CMake
changes or updates, and CMake policies change.
The most recent policy change was IMPORT_LOCATION, which is now
mandatory for interface libraries. An old CMake configuration cache
doesn't reflect the import library IMPORT_LOCATION property, which
caused confusing warning messages. The cure is removing the old cache
and reconfiguring.
- find gnu-getopt when installed by homebrew in /opt
- invoke realpath only on known path components
(needed for some realpath implementation(s))
(relevant when build-flavor directory does not yet exist)
- Bump SIMH_VERSION_MINOR in CMakeLists.txt. This propagates down
through the rest of the CMake infrastructure.
- README-CMake.md, cmake/{GitHub-release.md,cmake-builder.sh}: Update
documentation. (Prettiness.)
- vcpkg.json: Update simh version-string. (Consistency.)
NOTE: Github CI/CD: There has to be an automated way to update version
numbers; researching.
* CMake build infrastructure
The squashed commit that builds and packages releases for the SIMH
simulator suite with CMake, version 3.14 or newer.
See README-CMake.md for documentation.
