# FindPackageMessage
|
|
# ------------------

#
|
|
#
|
|
#
|
|
# FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")
|
|
#
|
|
# This macro is intended to be used in FindXXX.cmake modules files. It
|
|
# will print a message once for each unique find result. This is useful
|
|
# for telling the user where a package was found. The first argument
|
|
# specifies the name (XXX) of the package. The second argument
|
|
# specifies the message to display. The third argument lists details
|
|
# about the find result so that if they change the message will be
|
|
# displayed again. The macro also obeys the QUIET argument to the
|
|
# find_package command.
|
|
#
|
|
# Example:
|
|
#
|
|
# ::
|
|
#
|
|
# if(X11_FOUND)
|
|
# FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
|
|
# "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
|
|
# else()
|
|
# ...
|
|
# endif()
