ImageMagick: dyld: Library not loaded. Reason: image not found

Question

I downloaded ImageMagick from https://www.imagemagick.org/script/download.php#macosx
extracted it to ~/Documents/software
my .profile looks like this:

export MAGICK_HOME="~/Documents/software/ImageMagick-7.0.7"
export DYLD_LIBRARY_PATH="$MAGICK_HOME/lib/"
export PATH="$MAGICK_HOME/bin:$PATH"

when I run convert I get:

dyld: Library not loaded: /ImageMagick-7.0.7/lib/libMagickCore-7.Q16HDRI.4.dylib
Referenced from: /Users/oa/Documents/software/ImageMagick-7.0.7/bin/convert
Reason: image not found Abort trap: 6

Any reason not to use **homebrew**? It is miles easier to manage all your packages that way - i.e. `brew install imagemagick` and you are done. — Mark Setchell, Nov 24 '17 at 18:37
Thanks @MarkSetchell, but the reason being I want to get to the bottom of this annoying error. — dev4life, Nov 24 '17 at 18:46
First, try using `$HOME` instead of `~` as that works in more shells. Second, try using `otool -L /Users/oa/Documents/software/ImageMagick-7.0.7/bin/convert` to see what your `convert` binary actually needs/wants. Also, try `DYLD_PRINT_LIBRARIES=1 DYLD_PRINT_LIBRARIES_POST_LAUNCH=1 convert ...` to debug dynamic link libraries. Finally, resort to **homebrew** ;-) — Mark Setchell, Nov 24 '17 at 20:38
Pleasure! Feel free to write up the bit that helped and put it as an answer for all to see. Good luck with your project! — Mark Setchell, Nov 25 '17 at 12:50

As suggested by @Mark Setchell, the solution was to replace ~ by $HOME. Therefore, the export commands should be:

export MAGICK_HOME="$HOME/Documents/software/ImageMagick-7.0.7"
export DYLD_LIBRARY_PATH="$MAGICK_HOME/lib/"
export PATH="$MAGICK_HOME/bin:$PATH"

For those who do not use brew, using otool -L shows the problem:
