fail to build on windows

[YongHee-Kim]

my environmental is windows7 with cmake and MingGW installed for GNU support.
`+visual studio community 2015 as compiler

build.jl fails at line 25
run('make')

I assume that this is due to cmke configuration error, which suppose to generate makefile but didn't

here is full log message

Note: checking out 'Chipmunk-7.0.0'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

git checkout -b

Yeah this seems like a problem with cmake. First make sure this directory exists C:/Users/Yonghee/.julia/v0.4/Chipmunk/deps/Chipmunk2D.

If so, is there a Makefile in that directory?

[YongHee-Kim]

It turns out using visual studio 15 as generator for cmake doesn't generate makefile.

So I've changed generator with cmake -G "MSYS Makefiles" command and generated makefile.

but make still fails with following error
