Do not modify cached CMAKE_CXX_FLAGS_RELEASE

Adding compiler's flags and force updating cached value
of release C++ flags lead to appending special compiler
flags on every edit of any CMakeList.txt.

For compile result this is harmless, but was annoying
slight modification of CMakeList.txt triggered full
project rebuild.

Now modified C++ flags are used for the whole subtree
starting from the project root, but this doesn't lead
to flags modified in cache.
