Fix Windows -- MinGW build

[amontoison]

Ok, all tests passed on Windows -- MinGW here, so the issue is maybe in my compilation script for Yggdrasil :thinking: My compilation script is:

cd "${WORKSPACE}/srcdir/nomad"
mkdir "${WORKSPACE}/path"
export PATH="${WORKSPACE}/path:$PATH}"
export WADF=${WORKSPACE}/srcdir/nomad/src/Attribute/WriteAttributeDefinitionFile.cpp
${CXX_FOR_BUILD} ${WADF} -o ${WORKSPACE}/path/WriteAttributeDefinitionFile

sed s/'set(CMAKE_INSTALL_PREFIX ${PROJECT_BINARY_DIR} CACHE PATH "..." FORCE)'// -i CMakeLists.txt

mkdir build
cd build

cmake -DBUILD_INTERFACE_C=ON \
    -DTEST_OPENMP=OFF \
    -DCMAKE_INSTALL_PREFIX=${prefix} \
    -DCMAKE_TOOLCHAIN_FILE=${CMAKE_TARGET_TOOLCHAIN} \
    -DCMAKE_BUILD_TYPE=Release ..
make -j${nproc}
make install

I think the sed is not necessary anymore:

if(CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT) set(CMAKE_INSTALL_PREFIX ${PROJECT_BINARY_DIR} CACHE PATH "..." FORCE) endif()

But it should be ok anyway.

Just a comment on the modifs for the new version.

For windows, libraries have the same file name as before (libnomadAlgos.dll,...) but for linux and OSX, the libraries have the version number in their name (libnomadAlgo.4.3.0.so,...) and symbolic links are put in the lib directory.

The modif is in another pull request.
