Start migration to meson buildsystem As of right now, new buildsystem is capable of creating clean, featureful builds on Linux x86_64 - but these are not equivalent of all that are exposed via autoconf yet. As new features will be added, it will gradually replace Autotools and build.sh. Preserve our existing structure of building a static library per "module", and then linking them together to create dosbox binary. Unlike automake, we don't need to create a library per subdirectory - it's entirely our pragmatic choice. As a result, we don't have multiple sub-libraries for e.g. hardware module: all files inside are handled by a single meson.build file (we can simplify this even further and make the project structure even flatter or deeper as needed. Create config.h.in template file - meson turns it into our new config.h file, filling it with information detected in meson.build scripts. Create new file for main function - this way it'll be easier to ignore this file for gtest builds (which will have their own main functions). Old main was renamed to sdl_main and is now declared as the very first function in dosbox.h file. Update elementary build documentation in README.md and CONTRIBUTING.md. Remove majority of content in the INSTALL file. Information in that file was either outdated or is now automatically verified by meson.build script.

default_options : ['cpp_std=c++14', 'b_ndebug=if-release'],
version : '0.77.0')
Add unit tests to meson buildsystem Meson treats tests a bit different than we did previously - each test suite is compiled in to separate test and meson provides its own cumulative report. We are ok with this - it's now easier to selectively run specific test instead of all of them. It's also possible to mark test suites as "expected to fail", which is useful sometimes.

Start migration to meson buildsystem As of right now, new buildsystem is capable of creating clean, featureful builds on Linux x86_64 - but these are not equivalent of all that are exposed via autoconf yet. As new features will be added, it will gradually replace Autotools and build.sh. Preserve our existing structure of building a static library per "module", and then linking them together to create dosbox binary. Unlike automake, we don't need to create a library per subdirectory - it's entirely our pragmatic choice. As a result, we don't have multiple sub-libraries for e.g. hardware module: all files inside are handled by a single meson.build file (we can simplify this even further and make the project structure even flatter or deeper as needed. Create config.h.in template file - meson turns it into our new config.h file, filling it with information detected in meson.build scripts. Create new file for main function - this way it'll be easier to ignore this file for gtest builds (which will have their own main functions). Old main was renamed to sdl_main and is now declared as the very first function in dosbox.h file. Update elementary build documentation in README.md and CONTRIBUTING.md. Remove majority of content in the INSTALL file. Information in that file was either outdated or is now automatically verified by meson.build script.

Add unit tests to meson buildsystem Meson treats tests a bit different than we did previously - each test suite is compiled in to separate test and meson provides its own cumulative report. We are ok with this - it's now easier to selectively run specific test instead of all of them. It's also possible to mark test suites as "expected to fail", which is useful sometimes.
