problem description

I finished a project on git and compiled it according to
cmake-DSKIA_DIR=C:depsskia-G Ninja.
ninja aseprite
but I changed
cmake-G "Visual Studio 14"..
some parameters I omitted to generate SLN after I opened VS2015 to generate the project
report to me
vs2015 library computer type "x64" and target computer type "X86" conflict warning
and a bunch of link errors

I wonder if my cmake doesn"t have a 32-bit version. How can I succeed in ninja? there"s something wrong with vs2015
