Subject: IMPORTANT FIX: be extra-careful here on WIN32, we do NOT want CMake
 to look in the system's PATH env var to search for ImageMagick's convert.exe,
 otherwise it is going to pick Microsoft Window's own convert.exe, which is
 used to convert FAT partitions to NTFS format ! Depending on the options
 passed to convert.exe, there is a good chance you would kiss your hard-disk
 good-bye.
