build_type: [None, Debug, Release]
cd conanfiles\mingw-make
conan create user/testing
cd ..\arm-gcc
conan create arm-gcc/4.9.3@user/testing -s os=none
cd ..\..\SampleProject
md build
cd build
conan install .. -s os=none
activate.bat
cmake -DCMAKE_TOOLCHAIN_FILE=arm-none-eabi-gcc.cmake -DCMAKE_BUILD_TYPE=Debug -DCONAN_DISABLE_CHECK_COMPILER=1 -G"MinGW Makefiles" ..
cmake --build .

after this, there should be a build Blinky.elf file in the build folder.
