Adding gitignore for generated files

Exporting binary tree to CMake registry

This eases integration with other applications making use
of gflags without needing to install it in the system.
find_package looks in the registry for existing software.

Configure and install CMake package configuration file to help find_package locate the gflags package.

Move public header files to src/ subdirectory. Copy them to <prefix>/include/<ns>/ upon installation.

Remove build tool related files, operating system packages, and move unit tests to separate subdirectory.
