cmake: Remove defaults for COMPONENT_SRCDIRS, COMPONENT_SRCS, COMPONENT_ADD_INCLUDEDIRS * Philosophical: "explicit is better than implicit". * Practical: Allows useful errors if invalid directories given in components as the defaults aren't always used. Also trims the -I path from a number of components that have no actual include directory. * Simplifies knowing which components will be header-only and which won't 2018-01-19 00:22:08 -05:00			`set(COMPONENT_SRCDIRS ".")`
