# FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME (DEFAULT_MSG|"Custom failure message") VAR1 ... )
|
|
# This macro is intended to be used in FindXXX.cmake modules files.
|
|
# It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
|
|
# it also sets the <UPPERCASED_NAME>_FOUND variable.
|
|
# The package is found if all variables listed are TRUE.
|
|
# Example:
|
|
#
|
|
# FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)
|
|
#
|
|
# LibXml2 is considered to be found, if both LIBXML2_LIBRARIES 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, the location is reported using the VAR1 argument, so
|
|
# here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
|
|
# If the second argument is DEFAULT_MSG, the message in the failure case will
|
|
# be "Could NOT find LibXml2", if you don't like this message you can specify
|
|
# your own custom failure message there.
