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.
This commits squashes a lot of commits from master
together, since most of them are just fixes or
enhancements for the original CMake commit. The
decisions was not to bloat the release/2.6 commit
history with these detours.
