 The default OpenMP runtime used depends on the compiler and platform used. GCC (on Linux and the Windows MinGW

+runtime. For MSVC `llvm-openmp` is recommended, though `llvm-openmp` requires use of the `/openmp:llvm` option.
+However, individual projects may force building against a different runtime through their build system configuration.
 
 On Linux, building against `libgomp` is recommended as the other OpenMP providers are backwards compatible with it.
 When packages are built against `libgomp`, it is possible to use both `libgomp` and `llvm-openmp` provider at runtime.
