Update cmake (#277)
This restructures the cmake a little bit to only find components if they are actually enabled. It also rearranges things to better group some related items. This change also fixes include directories for the build target allowing the library to be embedded making the install step optional. Signed-off-by: Ben Magistro <koncept1@gmail.com>
