1 # FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME (DEFAULT_MSG|"Custom failure message") VAR1 ... )
2 # This macro is intended to be used in FindXXX.cmake modules files.
3 # It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
4 # it also sets the <UPPERCASED_NAME>_FOUND variable.
5 # The package is found if all variables listed are TRUE.
8 # FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)
10 # LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and
11 # LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE.
12 # If it is not found and REQUIRED was used, it fails with FATAL_ERROR,
13 # independent whether QUIET was used or not.
14 # If it is found, the location is reported using the VAR1 argument, so
15 # here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
16 # If the second argument is DEFAULT_MSG, the message in the failure case will
17 # be "Could NOT find LibXml2", if you don't like this message you can specify
18 # your own custom failure message there.
