Subject: [PATCH] Do not build the tests by default (CMake)

Issue #281 (bdwgc).

build_cord and build_tests options are introduced in the CMake script.

* CMakeLists.txt (build_cord): Add option (on by default); add comment.
* CMakeLists.txt (build_tests): Add option (off by default).
* CMakeLists.txt (cord): Specify add_subdirectory only if build_cord.
* CMakeLists.txt (tests): Specify add_subdirectory only if build_tests.
* cord/CMakeLists.txt: Skip cordtest and de tests unless build_tests.
