igraph C 语言 在 Windows 上的安装 （MINGW64）
NOTES: When using MSYS2, start the “MSYS2 MinGW 64-bit” terminal, and not the “MSYS2 MSYS” one.
参考：
https://igraph.org/c/doc/igraph-Installation.html#igraph-Installation-msys2
使用下面的命令更新软件包：
$ pacman --disable-download-timeout -Syuu $PACKAGES
$PACKAGES 取下面的包名.
必须要求：
mingw-w64-x86_64-toolchain
必须安装 mingw64 的 cmake （不能使用windows上的【如果有】）
mingw-w64-x86_64-cmake
把功能配置拉满，强烈建议：
mingw-w64-x86_64-gmp mingw-w64-x86_64-libxml2
追求极致性能，强烈建议：
mingw-w64-x86_64-openblas mingw-w64-x86_64-arpack mingw-w64-x86_64-glpk
仅开发版使用：
diffutils git bison flex
以上安装完毕，检查：
$ cmake --versioncmake version 3.31.2
CMake suite maintained and supported by Kitware (kitware.com/cmake).$ which cmake/mingw64/bin/cmake
编译 igraph 动态库
下载后解压：
https://github.com/igraph/igraph/releases/download/0.10.15/igraph-0.10.15.tar.gz
$ cd igraph-0.10.15/
$ mkdir build
$ cd build
# cmake -G "MSYS Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
实际使用下面的设置(-G “MSYS Makefiles” 指示生成 Makefile)：
$ cmake .. -G "MSYS Makefiles" \-DCMAKE_INSTALL_PREFIX=/usr/local/igraph \-DCMAKE_BUILD_TYPE=Release \-DIGRAPH_USE_INTERNAL_BLAS=OFF \-DIGRAPH_USE_INTERNAL_LAPACK=OFF \-DIGRAPH_USE_INTERNAL_ARPACK=OFF \-DIGRAPH_USE_INTERNAL_GLPK=OFF \-DIGRAPH_USE_INTERNAL_GMP=OFF \-DIGRAPH_USE_INTERNAL_PLFIT=ON \-DBLA_VENDOR=OpenBLAS \-DIGRAPH_GRAPHML_SUPPORT=ON \-DIGRAPH_ENABLE_LTO=ON \-DBUILD_SHARED_LIBS=ON

最后开始编译正式优化完全功能版的动态库并安装到指定位置（-DCMAKE_INSTALL_PREFIX=/usr/local/igraph）：
$ make
$ make install
