* Major CMake refactor * CI fixes * Fix CMake errors * Install graphviz on Windows * More consistent CMake build types * Fix compiler defines for Windows * Fix more bugs * Add standalone tool building support * Fix typo * Update README * Install sleighLift before trying to smoketest it * Test coverage preset The compiler option '-fkeep-inline-functions' originally included with the coverage build type causes errors with the message "undefined reference to 'vtable for OpAction*'" for all OpAction subclasses. This StackOverflow answer might help in resolving this? https://stackoverflow.com/a/57504289 * Build documentation by default with CI presets * Use COMPONENT for install commands This allows for someone to specify which components they want to install if they only want or need a subset * Support cross compiling with host system sleigh compiler * Various fixes found during review * Move "_WINDOWS" define to CMakeLists.txt file * Rename ToB 'tools' directory to 'extra-tools' * Separate projects for sleigh tools Library is still top-level CMakeLists.txt More options * CMake find_package(Git) * Fix bad merge for patch paths * Fix missing libconfig.h header install * Fix issues with installation of headers * More refactoring * Refactor sleighexample into its own project/directory * Refactor specfiles building into separate project/directory * Check for termios.h header and set define if found * Update READMEs * Better consistency with install rules * Build sleighLift as a standalone project with added source * More changes to CMake subprojects * Also add "Specs" component to sleigh installation config * Try to be better at bootstrapping subprojects (hopefully this doesn't bite us, but if it does, I'm happy to remove it and say "not supported") * Address some code review * Add project sleigh_tool for tool subdirectory Could make it easier to build just the tools * Add help text to name the tool executable name * Add license notice to CMake files * Fix/Remove too specific CPack packaging configuration * Consistent capitalization of Sleigh Co-authored-by: Alex Cameron <asc@tetsuo.sh>
