[CMake] OPTION-like combobox

[Pau Garcia i Quiles]

Hello,

Is there anything like OPTION but which allows to select one value
from a limited list of values (a combobox). Something like:

OPTION( CRYPTOBACKEND "Select a cryptography backend" VALUES "OpenSSL"
"LibTomCrypt" "LibDES" DEFAULT "OpenSSL" )
