Bug: With MSVC, the samples will always prefer freeglut.lib even with a debug build

[PavelSharp]

Describe the bug
A clear and concise description of what the bug is.
Files such as SimpleOpenGL/CMakeLists.txt and SimpleTexturedOpenGL/CMakeLists.txt contain are very similar section of code which seems to have an inaccuracy.
Consider

FIND_PACKAGE(GLUT)

IF ( NOT GLUT_FOUND )
  IF ( MSVC )
    SET ( GLUT_FOUND 1 )
    SET ( GLUT_INCLUDE_DIR ${Assimp_SOURCE_DIR}/samples/freeglut/ )
    SET ( GLUT_LIBRARIES ${Assimp_SOURCE_DIR}/samples/freeglut/lib/freeglut.lib )
  ELSE ()
    MESSAGE( WARNING "Please install glut." )
  ENDIF ()
ENDIF ()

Suppose we are starting a DEBUG(i.e. CMAKE_BUILD_TYPE = Debug) build in Windows using the MSVC compiler. This causes the assimp library to use a debugging runtime-library. However, by default, freeglut.lib prefer release runtime library.

To Reproduce
Steps to reproduce the behavior:

1. Download assimp
2. Download and build freeglut (with Debug and Release) and install both version in assimp/samples/freeglut
3. Build assimp with the -DASSIMP_BUILD_SAMPLES=ON in Debug mode

Expected behavior
The CMakeLists.txt of these samples must automatically choose between freeglut.lib and freeglutd.lib

Platform (please complete the following information):

• Windows, MSVC

Additional context
In general, according to my opinion, it all looks wierd. Because, FindGLUT.cmake, trying to find glut.h but these samples use freeglut.h. Am I missing something?
