[PATCH v4 3/8] cmake: installation support for git

["Sibi Siddharthan via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Sibi Siddharthan <sibisiddharthan.github@xxxxxxxxx>

Install the built binaries and scripts using CMake

This is very similar to `make install`.
By default the destination directory(DESTDIR) is /usr/local/ on Linux
To set a custom installation path do this:
cmake `relative-path-to-srcdir`
	-DCMAKE_INSTALL_PREFIX=`preferred-install-path`

Then run `make install`
