further simplifications/improvements
* bump to CMake 3.10 * only support the CMake standard way to define variables via `-DFOO=On` and not via the environment * clean-up switches only used for unit tests * mingw's ID is "GNU", so we match on the full compiler name instead * use CMake variables instead of environment variables via `$ENV{<stuff>}` * unconditionally set {C,LD}FLAGS passed by user * clean-up duplicate CPack keys + add FreeBSD config Signed-off-by: Steffen Jaeckel <s@jaeckel.eu>
