Windows support

[tsadakane]

Please forgive me for opening a similar PR even though @chobby has opened PR #246 for Issue #245.

This PR includes

• commit e68e82c
• More CMake options
• Possible to build tests and examples

You can build and test by the following steps:

1. make a working dir.

root
 +-- libcmaes  <= your workspace.
 +-- tools
        +-- build_libcmaes.sh 

"build_libcmaes.sh" is...

#!/bin/bash
# Choose one triplet from the three 
# triplet="x64-windows"
# triplet="x64-windows-static"
triplet="x64-windows-static-md"

build_type="Release"

pushd ..

if [ ! -d "vcpkg" ]; then
    git clone https://github.com/microsoft/vcpkg.git vcpkg
    pushd vcpkg
    ./bootstrap-vcpkg.sh -disableMetrics
    popd
fi

pushd vcpkg
./vcpkg.exe install eigen3:${triplet}

# Build and install
cmake --build . --config ${build_type}
cmake --install . --config ${build_type}

# Run tests
if [ $MAKE_DYNAMIC_LIB = "ON" ]; then
    # Copy glolg.dll, gflags.dll, cmaes.dll to tests/Release
    cp ${CURRENT}/vcpkg/installed/${triplet}/bin/glog.dll ${CURRENT}/build/tests/${build_type}
    cp ${CURRENT}/vcpkg/installed/${triplet}/bin/gflags.dll ${CURRENT}/build/tests/${build_type}
    cp ${CURRENT}/build/src/Release/cmaes.dll ${CURRENT}/build/tests/${build_type}
fi
cd tests/${build_type}
./test-functions.exe --all

popd

2. Select one of the triplets in build_libcmaes.sh
3. Run build_libcmaes.sh
   • test-functions --all will run at the end.

I found that LIBCMAES_USE_GLOG option does not work as expected. I'm working on it.

@tsadakane I have a running build with conan on windows in #234 if you want to use that
