yaml-cpp/CMakeLists.txt
Sam Kellett f008774edc Made version.h static and version_test.cpp dynamic.
Switched around the header and unit test. Now the unit test is created by CMake using the variables
set in there and the version.h header is created manually. Unit test checks that both the CMake
variables and header share the same version.
