### Install rules
#   Install the freshly compiled software, and correct the pkg_config files.
#   This installation will be used to configure and compile other pieces of softwares. This is
#   not the target directory, theses files are copied in the stating directory.
# Target are executed in the following order:
#  install_msg_target
#  $(PRE_INSTALL_PLIST)
#  pre_install_target              (override with PRE_INSTALL_TARGET)
#  install_target                  (override with INSTALL_TARGET)
#  post_install_target             (override with POST_INSTALL_TARGET)
#  $(INSTALL_PLIST)
#  install_correct_lib_files
# Variables:
#  INSTALL_PREFIX          Target directory where the software will be run.
#  INSTALL_DIR             Where to install files. INSTALL_PREFIX will be added.
#  STAGING_INSTALL_PREFIX  Where to instll files, in extenso. 
# Files:
#  $(WORK_DIR)/$(PKG_NAME).plist   List of files installed. Can be used to build the PLIST file
#                                  of each software.
