Hi Eh2406,

There is code in place to use CMake on Windows, but I do not know if this works. Can you try installing CMake and then running cargo build in a clone of the rust-pcre repository?

I will try to find a Windows machine that I can use to test.

Installed CMake on path.

CMake Error at CMakeLists.txt:69 (PROJECT):
  The CMAKE_C_COMPILER:

    cl

  is not a full path and was not found in the PATH.

  To use the NMake generator with Visual C++, cmake must be run from a shell
  that can use the compiler cl from the command line.  This environment is
  unable to invoke the cl compiler.  To fix this problem, run cmake from the
  Visual Studio Command Prompt (vcvarsall.bat).

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.

Looks like it is trying to compile with Visual Studio witch wont be compatible with Windows (GNU ABI †) even if it had worked.
