# The purpose of this file is to set the default installation layout.
# Currently, there are 2 different installation layouts ,
# one is used in tar.gz packages (Windows zip is about the same), another one 
# in RPMs.

# There are currently 2 layouts defines, named STANDALONE (tar.gz layout)
# and UNIX (rpm layout). To force a directory layout when invoking cmake use
# -DINSTALL_LAYOUT=[STANDALONE|UNIX].
# This wil use a predefined layout. There is a possibility to further fine-tune 
# installation directories. Several variables are can be overwritten
#
# - INSTALL_BINDIR     (directory with client executables and Unix shell scripts)
# - INSTALL_SBINDIR    (directory with mysqld)
# - INSTALL_LIBDIR     (directory with client end embedded libraries)
# - INSTALL_PLUGINDIR  (directory for plugins)
# - INSTALL_INCLUDEDIR (directory for MySQL headers)
# - INSTALL_DOCDIR     (documentation)
# - INSTALL_MANDIR     (man pages)
# - INSTALL_SCRIPTDIR  (several scripts, rarely used)
# - INSTALL_MYSQLSHAREDIR (MySQL character sets and localized error messages)
# - INSTALL_SHAREDIR  (location of aclocal/mysql.m4)
# - INSTALL_SQLBENCHDIR (sql-bench)
# - INSTALL_MYSQLTESTDIR (mysql-test)
# - INSTALL_DOCREADMEDIR (readme and similar)
# - INSTALL_SUPPORTFILESDIR (used only in standalone installer)

# Default installation layout on Unix is UNIX (kent wants it so)
