91################################### WARNING! ###################################
92# It seems that you are trying to install Perl::Magick on a MS Windows box with
93# perl + gcc compiler (e.g. strawberry perl), however we cannot find ImageMagick
94# binaries installed on your system.
95#
96# Please check the following prerequisites:
97#
98# 1) You need to have installed ImageMagick Windows binaries from
99#    http://www.imagemagick.org/script/binary-releases.php#windows
100#
101# 2) We only support dynamic (DLL) ImageMagick binaries
102#    note: it is not possible to mix 32/64-bit binaries of perl and ImageMagick
103#
104# 3) During installation select that you want to install ImageMagick's
105#    development files (libraries+headers)
106#
107# 4) You also need to have ImageMagick's directory in your PATH
108#    note: we are checking the presence of convert.exe and/or identify.exe tools
109#
110# 5) You might need Visual C++ Redistributable Package installed on your system
111#    see instructions on ImageMagick's Binary Release webpage
112#
113# We are gonna continue, but chances for successful build are very low!
