The first argument in both modes is -# the name of the Find-module where it is called (in original casing). -# -# The first simple mode looks like this: -# FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> (DEFAULT_MSG|"Custom failure message") <var1>...<varN> ) -# If the variables <var1> to <varN> are all valid, then <UPPERCASED_NAME>_FOUND -# will be set to TRUE. -# If DEFAULT_MSG is given as second argument, then the function will generate -# itself useful success and error messages. You can also supply a custom error message -# for the failure case. This is not recommended. -# -# The second mode is more powerful and also supports version checking: -# FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME [REQUIRED_VARS <var1>...<varN>] -# [VERSION_VAR <versionvar> -# [FAIL_MESSAGE "Custom failure message"] ) -# -# As above, if <var1> through <varN> are all valid, <UPPERCASED_NAME>_FOUND -# will be set to TRUE. -# Via FAIL_MESSAGE a custom failure message can be specified, if this is not -# used, the default message will be displayed. -# Following VERSION_VAR the name of the variable can be specified which holds -# the version of the package which has been found. If this is done, this version -# will be checked against the (potentially) specified required version used -# in the find_package() call. The EXACT keyword is also handled. The default -# messages include information about the required version and the version -# which has been actually found, both if the version is ok or not. -# -# Example for mode 1: -# -# FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR) -# -# LibXml2 is considered to be found, if both LIBXML2_LIBRARY and -# LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE. -# If it is not found and REQUIRED was used, it fails with FATAL_ERROR, -# independent whether QUIET was used or not. -# If it is found, success will be reported, including the content of <var1>. -# On repeated Cmake runs, the same message won't be printed again. -# -# Example for mode 2: -# -# FIND_PACKAGE_HANDLE_STANDARD_ARGS(BISON REQUIRED_VARS BISON_EXECUTABLE -# VERSION_VAR BISON_VERSION) -# In this case, BISON is considered to be found if the variable(s) listed -# after REQUIRED_VAR are all valid, i.e. BISON_EXECUTABLE in this case. -# Also the version of BISON will be checked by using the version contained -# in BISON_VERSION. -# Since no FAIL_MESSAGE is given, the default messages will be printed. -
