[CMake] CMake and SWIG

[David Cole]

If you open the file "C:/Program Files/CMake
2.8/share/cmake-2.8/Modules/FindSWIG.cmake" and read through it, you will
see exactly where CMake is looking for SWIG.

It uses:

FIND_PROGRAM(SWIG_EXECUTABLE swig)

(which means it's only looking in the PATH...)

So you can either:

  set(SWIG_EXECUTABLE "C:/full/path/to/swig.exe")
  # (before FIND_PACKAGE(SWIG REQUIRED))

or:

  have swig.exe available somewhere in the PATH environment variable...


HTH,
David
