[CMake] Extra blank lines with SEND_ERROR and FATAL_ERROR ?!

[Marcel Loose]

Hi all,

When using SEND_ERROR and FATAL_ERROR, extra blank lines are added
between newline-separated strings. I don't really like this. Is it
intentional, or is this a formatting bug?

For example, the CMakeLists.txt file:

cmake_minimum_required(VERSION 2.6)
project(Dummy NONE)
message(STATUS      "Line one\nLine two\nLine three")
message(SEND_ERROR  "Line one\nLine two\nLine three")
message(FATAL_ERROR "Line one\nLine two\nLine three")

produces the following output on console:

-- Line one
Line two
Line three
CMake Error at CMakeLists.txt:4 (message):
  Line one

  Line two

  Line three


CMake Error at CMakeLists.txt:5 (message):
  Line one

  Line two

  Line three


-- Configuring incomplete, errors occurred!

As can be seen, SEND_ERROR and FATAL_ERROR add extra blank lines.

Best regards,
Marcel Loose.
