It also sets the <packagename>_FOUND variable. The -# package is considered found if all variables <var1>... listed contain -# valid results, e.g. valid filepaths. -# -# There are two modes of this function. 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 -# [FOUND_VAR <resultVar>] -# [REQUIRED_VARS <var1>...<varN>] -# [VERSION_VAR <versionvar>] -# [HANDLE_COMPONENTS] -# [CONFIG_MODE] -# [FAIL_MESSAGE "Custom failure message"] ) -# -# In this mode, the name of the result-variable can be set either to -# either <UPPERCASED_NAME>_FOUND or <OriginalCase_Name>_FOUND using the -# FOUND_VAR option. Other names for the result-variable are not -# allowed. So for a Find-module named FindFooBar.cmake, the two -# possible names are FooBar_FOUND and FOOBAR_FOUND. It is recommended -# to use the original case version. If the FOUND_VAR option is not -# used, the default is <UPPERCASED_NAME>_FOUND. -# -# As in the simple mode, if <var1> through <varN> are all valid, -# <packagename>_FOUND will be set to TRUE. After REQUIRED_VARS the -# variables which are required for this package are listed. 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. If the package supports components, use the -# HANDLE_COMPONENTS option to enable handling them. In this case, -# find_package_handle_standard_args() will report which components have -# been found and which are missing, and the <packagename>_FOUND variable -# will be set to FALSE if any of the required components (i.e. not the -# ones listed after OPTIONAL_COMPONENTS) are missing. Use the option -# CONFIG_MODE if your FindXXX.cmake module is a wrapper for a -# find_package(... NO_MODULE) call. In this case VERSION_VAR will be -# set to <NAME>_VERSION and the macro will automatically check whether -# the Config module was found. Via FAIL_MESSAGE a custom failure -# message can be specified, if this is not used, the default message -# will be displayed. -# -# 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(LibXslt -# FOUND_VAR LibXslt_FOUND -# REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS -# VERSION_VAR LibXslt_VERSION_STRING) -# -# In this case, LibXslt is considered to be found if the variable(s) -# listed after REQUIRED_VAR are all valid, i.e. LibXslt_LIBRARIES and -# LibXslt_INCLUDE_DIRS in this case. The result will then be stored in -# LibXslt_FOUND . Also the version of LibXslt will be checked by using -# the version contained in LibXslt_VERSION_STRING. Since no -# FAIL_MESSAGE is given, the default messages will be printed. -# -# Another example for mode 2: -# -# :: -# -# find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4) -# find_package_handle_standard_args(Automoc4 CONFIG_MODE) -# -# In this case, FindAutmoc4.cmake wraps a call to find_package(Automoc4 -# NO_MODULE) and adds an additional search directory for automoc4.
