[CMake] @ONLY and nested variables

[Ruslan Baratov]

You can run configure_package_config_file twice with code:

SET(@PACKAGE at _LIBS @@PACKAGE at _LIBRARIES@)

Also you can use configure_file command to create one file and include 
it with config file that was made by configure_package_config_file:

# CMakeLists.txt
configure_file(FooVars.cmake.in FooVars.cmake)
configure_package_config_file(FooConfig.cmake.in FooConfig.cmake ...)

install(FILES FooVars.cmake FooConfig.cmake ...)

# FooConfig.cmake.in
include(relative/path/to/FooVars.cmake)
