Is it possible to change the visual studio 2015 compiler to Cygwin the ide is nice I would just like a different compiler.
Not directly, but you can use CMake to generate both Cygwin and Visual Studio projects. Write code in Visual Studio, build the Cygwin build via CMake. Only downside: updates to the Visual Studio
.vcxproj file aren't sync'ed back to the CMakelist.txt file.
