# FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ... ) |
|
# |
|
# This function is intended to be used in FindXXX.cmake modules files. |
|
# It handles the REQUIRED, QUIET and version-related arguments to FIND_PACKAGE(). |
|
# It also sets the <UPPERCASED_NAME>_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 [REQUIRED_VARS <var1>...<varN>] |
|
# [VERSION_VAR <versionvar> |
|
# [CONFIG_MODE] |
|
# [FAIL_MESSAGE "Custom failure message"] ) |
|
# |
|
# As above, if <var1> through <varN> are all valid, <UPPERCASED_NAME>_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. |
|
# Use the option CONFIG_MODE if your FindXXX.cmake module is a wrapper for |
|
# a find_package(... NO_MODULE) call, in this case all the information |
|
# provided by the config-mode of find_package() will be evaluated |
|
# automatically. |
|
# 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(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. |
|
# |
|
# 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. |
|
# The following FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper |
|
# success/error message. |
