Subject: [PATCH] CMakeLists.txt: explicitly enable the CMP0067 (C/C++ standard
 flags) policy

Explicitly enable the CMP0067 policy to have try_compile use the correct
C/C++ standard flags; otherwise, CMake will default to not honoring those,
causing the C/C++ checks to be compiled with no standard flags and SimGear
to be compiled with them. This causes errors if we try to detect a new
prototype which is only present in C++14 and above).
