[CMake] Examples creating exported Makefiles and correct library link order

[J Decker]

I wrote a C script that I configure_file on that writes a cmakelists
module (might also be a makefile)

(I think) The cmake way would be to define PROJECT_LIBRARIES;
PROJECT_INCLUDE_DIR; PROJECT_LIBRARY_DIR; PROJECT_INCLUDE_DIR... all
of which can be built from knowing CMAKE_INSTALL_PREFIX

but you have to recreate by hand where you installed things to to
append to the CMAKE_INSTALL_PREFIX to get the appropriate things.
Also I think you can get the current directory that the makefile is
in, so you could build makefile references from whereever it happens
to be at the time that way.

CMAKE_INSTALL_CONFIG_NAME might also be of use for distributing
debug/release libraries... ./include/Project, ./lb/Project/Debug,
./lib/Project/Release ,....
