I'm not sure if this should be posted here or if I should go upstream 
to cmake.org but I was compiling an application that uses cmake/ccmake 
and can be compiled on Windows/Linux/MingW/Cygwin and so on.  Not a lot 
of folks try it on Cygwin so I have been stumbling over some of the 
issues.  Anyways - one of its checks is to look for wxWidgets which I 
don't have and don't believe is a package for Cygwin anyways but cmake 
kept insisting it was on D:/wxWidgets....Some directory which appears 
to a default in the FindwxWidgets.cmake script.

Digging deeper and googling for various info I found this in the 
script:

#=====================================================================
#=====================================================================
IF(WIN32)
  SET(WIN32_STYLE_FIND 1)
ENDIF(WIN32)
IF(MINGW)
  SET(WIN32_STYLE_FIND 0)
  SET(UNIX_STYLE_FIND 1)
ENDIF(MINGW)
IF(UNIX)
  SET(UNIX_STYLE_FIND 1)
ENDIF(UNIX)

where apparently the STYLE_FIND variables control whether it searches 
(Win32/Registry) or uses the wxWidget config file (Unix).

If I understand what I seem to have seen in config scripts for Cygwin 
before - in Cygwin both WIN32 and CYGWIN are set just as above it 
appears they are in MINGW.  When I added this code:

IF(CYGWIN)
  SET(WIN32_STYLE_FIND 0)
  SET(UNIX_STYLE_FIND 1)
ENDIF(CYGWIN)

right after the MINGW routine that stopped cmake from finding wxWidget 
or defaulting.

Just thought I would pass this on for the cmake maintainer.
