| 3 | # This macro is intended to be used in FindXXX.cmake modules files.
|
---|
| 4 | # It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
|
---|
| 5 | # it also sets the <UPPERCASED_NAME>_FOUND variable.
|
---|
| 6 | # The package is found if all variables listed are TRUE.
|
---|
| 7 | # Example:
|
---|
| 8 | #
|
---|
| 9 | # FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)
|
---|
| 10 | #
|
---|
| 11 | # LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and
|
---|
| 12 | # LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE.
|
---|
| 13 | # If it is not found and REQUIRED was used, it fails with FATAL_ERROR,
|
---|
| 14 | # independent whether QUIET was used or not.
|
---|
| 15 | #
|
---|
| 16 | # If it is found, the location is reported using the VAR1 argument, so
|
---|
| 17 | # here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
|
---|
| 18 | # If the second argument is DEFAULT_MSG, the message in the failure case will
|
---|
| 19 | # be "Could NOT find LibXml2", if you don't like this message you can specify
|
---|
| 20 | # your own custom failure message there.
