Windows Compilation

a.markdown

I have a lib I am trying to link against at:

hitt\ext\hittsdk\H-ITTSDK_2.0.4\lib\windows\h-ittsdk.dll

It can find the header file at:

hitt\ext\hittsdk\H-ITTSDK_2.0.4\include\H-ITTSDK.h

I have this working on my Mac, but I need to now get it working on windows.

extconf.rb

require 'mkmf'

source_dir = File.expand_path RbConfig::CONFIG['srcdir']

if RUBY_PLATFORM =~ /win32|mingw/i
	hitt_folder = "windows"
else
	hitt_folder = "macosx"
end

dir_config('hitt_sdk', source_dir + "/H-ITTSDK_2.0.4/include", source_dir + "/H-ITTSDK_2.0.4/lib/#{hitt_folder}")

unless find_header("H-ITTSDK.h")
	abort "H-ITTSDK is missing!!!"
end

unless find_library("h-ittsdk", "hitt_sdk_version")
	abort "libH-ITTSDK is missing!!!"
end

create_makefile("hittsdk/hittsdk")
