Re-fix problem exposed by recent commit to FindPythonInterp. If the find "details" has new lines in it, then replace them with the empty string so that the string may be saved as a cache entry that can be re-read next time CMake runs. Use REGEX REPLACE, and replace with an empty string, eliminating the problem characters, so that we may easily extend this to include additional problem characters in the future if necessary.

# 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(X11_FOUND)
|
|
# ...
|
|
# ENDIF(X11_FOUND)
