Change Details

This adds a CMake build script to be run by Travis. Since some configuration switches are not part of the CMake options, some builds are redundant, which is not perfect. Also the `BUILD` and `EXTRAFLAGS` cases are not handled since CMake has different targets/variables to achieve the same result. This can be improved later. Depends on D4855.
