# FindPackageMessage
# ------------------

ENH: Added FindPackageMessage module - Defines FIND_PACKAGE_MESSAGE function to help display find result messages only once - Added use of it to FindPackageHandleStandardArgs - Added use of it to FindQt4, and FindX11 - This cleans up repeated messages in big projects

# 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.

Convert CMake find-modules to BSD License This adds copyright/license notification blocks CMake's find-modules. Many of the modules had no notices at all. Some had notices referring to the BSD license already. This commit normalizes existing notices and adds missing notices.

Convert CMake-language commands to lower case Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case.
