Feature request: REQUIRED for all find_* functions

find_package() has the flag REQUIRED. If it is set, the configuration fails when the package cannot be found.
I think this flag should be available for all find_* functions. This reduces duplicate code like

find_program(MYEXE myexe)
    status(FATAL_ERROR "myexe has not been found")

Additionally, the variable <VAR>_FOUND should be set in each find_* function so the error handling code for is the same for optional find_program() and optional find_package().

What do you think?
