Our CMake code should be rewritten to not expect things as strings
that really aren't, but this would entail a whole lot of cross-
platform testing, so I'm postponing it for now.
- Relax version checking because we intend to have only a single branch
- Exclude ldfpu.asm from build with MSVC-32 (reported by huynh van sen)
- Fix FindLLVM.cmake to work on Windows again
The current code to locate libconfig++ has some trouble:
- It is located in the main CMakeList file but should be a module of its own
- It depends on pkg-config which is not available on Windows
- The returned values are not really useful therefore the library name is hard coded
This commit tries to solve these problems. For a Unix-like system there should be no difference.
Additionally, you can override the variables on the command line which is useful for builds on Windows.
