Yes, it could be done this way, but Matlab actually has non-standard
layout for include/lib directories, so both CMAKE_INCLUDE_PATH and
CMAKE_LIBRARY_PATH have to get employed.  But more importantly, this
way the knowledge of this and other (like names of 32/64 bit library
directories) stuff migrates from CMake module, where it belongs, to
the script the developer is sourcing in his shell in order to setup
the environment, and seems to me that this is really not the right
approach.
