This is based on the initial CMake patch by Arne Schwabe, but extends that to provide a complete replacement for existing MinGW build (autotools based) and MSVC build (openvpn.sln). The following features are added while switching these builds to CMake: - vcpkg support for MinGW build, allowing for trivial cross-compilation on Linux - Add unittests to MSVC build - Rework MSVC config header generation, removing need for separate headers between autotools and MSVC The following advantages are reasons for switching to CMake over the existing MSVC build: - Easier to maintain CMake files without IDE than the sln and vcxproj files - Able to maintain MSVC and MinGW build side-by-side The plan is to completely remove the existing MSVC build system but leave the existing autotools builds in place as-is, including MinGW support. CMake is not the intended build system for Unix-like platforms and there are no current plans to switch to it. v2: - Reduce default warning level for MSVC to /W2. With /W3 the build is just much too noisy, making it difficult to spot new warnings. - Change MSVC CMake presets to have hardcoded build type. When using pkg_search_module MSVC Multi-Config builds do not work correctly at all since PkgConfig doesn't seem to be able to create multi-config libraries like find_package does. - Change minGW presets to be Multi-Config capable. - Remove OPENVPN_VERSION_MAJOR, OPENVPN_VERSION_MINOR, OPENVPN_VERSION_PATCH from config.h.cmake.in. They are not required and cause macro redefinition warnings in MSVC (with openvpn-plugin.h). gcc doesn't warn about this because the definitions are identical so no need to fix this in autoheader config.h.in. v3: - Apply fixes by Lev Stipakov to match MSVC compile options better to previous build. - Apply change by Lev Stipakov to enable generation of PDB files. - Move /Brepro to its own commit. This is a behavior change that should be more visible. - Rebase on top of my dist fixes.
