[CMake] EXECUTE_PROCESS too good at running programs

There are ~30 tools in E:\msys\1.0\bin that do not have .exe suffixes, run fine under a MSYS shell, and are not intended to be run under anything but a MSYS shell.  EXECUTE_PROCESS is finding a way to run them.  My wild-assed-guess as to explanation, is that it execs arbitrarily named files, and does not check whether the filename is valid for a Windows command prompt.  These MSYS tools are probably valid apps in some Windows-native sense, but not to a Windows command prompt.

I'm sure you and Brad do.  That doesn't mean an installation with plain 
old "makeinfo" is invalid.  For instance, I believe I may have built and 
installed makeinfo from source, under the MSYS shell.  It works fine 
under MSYS shell and the CMake MSYS generator, no problemo.  As I said 
in a previous e-mail, there are 30 tools in my E:\msys\1.0\bin that do 
not have .exe suffixes.  I believe I obtained them from standard MSYS 
tarballs; I certainly didn't compile them.  This is a general problem 
for MSYS and VC++ interactions.  It is not specific to my particular 
"makeinfo".

Not relevant; let's not add any Cygwin shell issues here.

This dual nature is interesting, but as my installation demonstrates, a 
singular nature is also possible.

msys:

Brandon J. Van Every at KAHLO /bin
$ ls -l makeinfo*
-rwxr-xr-x    1 Brandon  Administ   180224 Apr 30  2004 makeinfo


Windows command prompt:

E:\msys\1.0\bin>dir makeinfo.*
 Volume in drive E is MONDRIAN
 Volume Serial Number is 9CA0-CADF

 Directory of E:\msys\1.0\bin

04/30/2004  11:15p             180,224 makeinfo
               1 File(s)        180,224 bytes
               0 Dir(s)  11,499,442,176 bytes free
