# 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).

# 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

# Example for mode 1:
