Provide forward compatible cmake paradigms Automatically extract version information from the zstd.h file. Use naming of variables consisent with modern cmake and https://semver.org/ (Semantic Versioning 2.0.0, MAJOR, MINOR, PATCH) Modern versions of cmake provide consistent paradigms for configuring project external interface values. This set of changes provide a back port of some of cmake 3+ paradigms back to cmake 2.8.9. Set and allow use of the current cmake policies for newer versions of cmake when available to allow for modern compiler features to be utilized when available. NOTE: The intent is that future modifications to cmake will enable (conditional on cmake version support) the ability to support modern linkage, and target export mechanisms. Those future changes will make incorporating zstd into other packages much easier. This patch also allows the more rigourous error checking of commmon cmake errors to be preformed by cmake (i.e. more stringent syntax checking and create errors for common hard to find misuses of cmake variables). This patch also provides support for modern compiler support options by cmake (like enabling interprocedural optimization if link time optimizations are known to be supported by the compiler envirionment. IPO can be supported by setting the CMAKE_INTERPROCEDURAL_OPTIMIZATION variable for newer versions of cmake.

Improve setting the default build type The CMAKE_BUILD_TYPE variable is a CACHE variable and should be set in a way that persists and is documented in the CACHE. Also set the default values for the gui to ease selection of types. These changes provide better support for GUI configurators that support cmake.
