#  TARGETS
#    all
#      Builds either a shared or a static library, depending of the value
#      of the SHARED variable.
#      Default: static
#
#    banner
#      Displays the library version and the target
#
#    install
#      Installs either the shared of the static library, depending of the value
#      of the SHARED variable. Installs the header files as well.
#      Builds the library before installing if it does not exist already.
#      Ececutes ldconfig in case of the shared library.
#      Default locations:
#        library: $(exec_prefix)/$(libdir) => /usr/lib
#        headers:   $(prefix)/$(includedir) => /usr/include
#
#    install_headers
#      Installs the header files.
#      Default location: $(prefix)/$(includedir) => /usr/include
#
#    clean
#      Removes the shared or the static library, depending of the value
#      of the SHARED variable, from this folder and all the folders and objects
#      which were created to build it.
#
#    uninstall
#      Removes the shared or the static library, depending of the value
#      of the SHARED variable from the system. In case of the shared library,
#      removes the symbolic links as well and executes ldconfig.
#
#    uninstall_headers
#      Remove the headers from the system.
#
#  Variables
#    prefix
#      The general installation root directory. Default: /usr
#
#    exec_prefix
#      The installation root directory to place executables and libraries.
#      Default: prefix
#
#    libdir
#      The directory where the libraries are installed, as a subdirectory of
#      exec_prefix. Default: lib
#
#    includedir
#      The directory where the header files are installed, as a subdirectory of
#      prefix. Default: include
#
#    srcdir
#      The directory where the object source files are located.
#      Default: _internal/Source
#
#    CXX
#      The compiler to be used. Default: c++
#
#    CXXFLAGS
#      The compiler flags used to compile the object files.
#      Default:
#        cxxflags_default for default
#        cxxflags_small   for BUILD_TYPE=small
#        cxxflags_debug   for BUILD_TYPE=debug
#
#    AR
#      The archiver to be used. Default: ar
#
#    PIC
#      The PIC to be used. Default: PIC
#
#    BUILD_TYPE
#      Used to select a specific set of predefined configuration parameters.
#      Default:  undefined: The default settings are used
#      Options:
#        small
#        debug
#
#    SHARED
#      Used to select if the library is a shared or a dynamic one
#      Default: undefined: static
#      Options:
#        0:         static
