# Configuration variables, all optional, are
#
# MYSQL_DIR - Set in environment or as parameter to "cmake",
# this is the top directory of the MySQL Server or
# Connector/C install
# MYSQL_INCLUDE_DIR - Set in environment or as parameter to "cmake",
# this is the include directory where to find
# the client library
# MYSQL_LIB_DIR - Set in environment or as parameter to "cmake",
# this is the library directory where to find
# the client library
# MYSQLCLIENT_STATIC_LINKING
# - Specify that you want static linking, dynamic
# linking is the default
# MYSQLCLIENT_NO_THREADS
# - Specify to link against the single threaded
# library, "libmysqlclient". Note that in 5.5
# and up "libmysqlclient" is multithreaded and
# "libmysqlclient_r" just a soft link to it
# MYSQL_CONFIG_EXECUTABLE
# - "mysql_config" executable to use
# MYSQL_CXX_LINKAGE - Specify that client library needs C++ linking
# MYSQL_EXTRA_LIBRARIES
# - Libraries to add to the linkage
# MYSQL_CFLAGS - C compiler flags
# MYSQL_CXXFLAGS - C++ compiler flags
# MYSQL_LINK_FLAGS - User defined extra linkage flags
# FINDMYSQL_DEBUG - Set if want debug output from this script
#
# Note that most variables above, if not set by the user they will be
# set by this include file.
#
# In addition, the below CMake variables are set by this include file
#
# MYSQL_VERSION - Three position numeric version, like 5.6.41
# MYSQL_VERSION_ID - Numeric padded version, 5.13.4 => 51304
# MYSQL_NUM_VERSION - Same as MYSQL_VERSION_ID, for compatibility
# MYSQL_LIB - Path to the client library
# MYSQL_LIBRARIES - Library name, might be "-lmysqlclient" while
# MYSQL_LIB is the path to the library
# MYSQL_CLIENT_LIBS - Same as MYSQL_LIBRARIES, for compatibility
#
# (1) If MYSQL_INCLUDE_DIR or MYSQL_LIB_DIR are given, these are
# used and an error is reported if can't be used
# (2) If MYSQL_CONFIG_EXECUTABLE is given, it is used to get
# headers and libraries
# (3) If MYSQL_DIR is given and "${MYSQL_DIR}/bin/mysql_config" is
# found, then same as (2)
# (4) If MYSQL_DIR is given and no "${MYSQL_DIR}/bin/mysql_config",
# search MYSQL_DIR
#
# FIXME if we get a "mysql_config" on Windows, things needs to change
# FIXME rename the VERSION variables above
# FIXME let MYSQL_VERSION include "-beta" etc?
# FIXME can mysql_config --version be C/C verson?
# FIXME if no mysql_config, find version from include/mysql_version.h?
# #define MYSQL_SERVER_VERSION "5.7.5-m15"
# #define MYSQL_VERSION_ID 50705
# #define LIBMYSQL_VERSION "6.1.5"
# #define LIBMYSQL_VERSION_ID 60105
# FIXME can MYSQL_LIB_DIR be a list of paths?
# FIXME is MYSQLCLIENT_LIBS a better name?
# FIXME cache variables, makes them command line args?
# FIXME really do include_directories() and link_directories()? Likely
# FIXME add check that if not static, not picked up .a or mysqlclient.lib
# FIXME MYSQL_VERSION_ID need to take into account Cluster versions
# and Connector/C versions
# FIXME handle MYSQL_VERSION_ID, LIBMYSQL_VERSION and LIBMYSQL_VERSION_ID?
