Crosscompiling using mingw:
mkdir build-mingw && cd build-mingw
TOOLCHAIN_PREFIX=i686-w64-mingw32 # check up the actual mingw prefix of your mingw installation
cmake ../ -DCMAKE_SYSTEM_NAME=Windows -DCMAKE_C_COMPILER="$TOOLCHAIN_PREFIX-gcc" -DCMAKE_CXX_COMPILER="$TOOLCHAIN_PREFIX-g++"
You may enable or disable some build options by -Dkey=value. All available build options are defined in CMakeLists.txt at root directory.
See below if you want to build the GoldSource compatible libraries.

Unlike original client by Valve the resulting client library will not depend on vgui or SDL2 just like the one that's used in FWGS Xash3d.
Note for **Windows**: it's not possible to create GoldSource compatible libraries using mingw, only msvc builds will work.
Note for **Linux**: GoldSource requires libraries (both client and server) to be compiled with libstdc++ bundled with g++ of major version 4 (versions from 4.6 to 4.9 should work).
If your Linux distribution does not provide compatible g++ version you have several options.
