Reference Lambert W Implementation

A robust reference implementation of the Lambert W function.

Building on Windows

This library depends on flint, MPFR and sleef. Since MPFR uses a make buildsystem, I recommend using vcpkg to manage this on Windows.

• First, use vcpkg to install mpfr and pkgconf
• Download, build, and install flint and sleef (from source or using vcpkg)
• Make sure to specify the following CMake variables before configuring
  • CMAKE_TOOLCHAIN_FILE = {VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake
  • PKG_CONFIG_EXECUTABLE = {VCPKG_ROOT}/installed/x64-windows/tools/pkgconf/pkgconf.exe
