I'm no windows expert but
as far as I know "triangle_lib.lib" is not a static lib but a lib needed
for compiling?or?linking a program which uses triangle_lib.dll.

triangle_lib.lib should be built along with triangle_lib.dll when compiling
the lib.

Is triangle_lib.dll generated properly in the build directory?

Normally you don't have to,
moreover in this case your lib is a CMake target of the same
project. CMake should find it without trouble.

Is your CMakeLists.txt just as you wrote it?
If you have 4 files you may post your whole project here?
Which version of CMake do you use?
