Generate package config files in cmake's current binary directory

Generate the config files of the package in CMAKE_CURRENT_BINARY_DIR instead of CMAKE_BINARY_DIR because the later will refer to the main project's binary directory if the library is included in the project using the add_subdirectory command.
