Summary0009879: find_program command doesn't take PATHEXT into account
DescriptionThe find_program command cannot find programs that don't use the .exe extension, for example .cmd scripts.

On Windows, the PATH environment variable is only part of what is used by the command line (and compatible programs) to determine what files are executable. The other part is the PATHEXT environment variable, which lists extensions of executable files.

The find_program command seems to assume that .exe is the only extension to check. It should be modified to extract the extension list from PATHEXT, and test all extensions listed there, in the same order as is the Windows command line evaluating them.

We should pay attention to the PATHEXT variable on Windows. Good observation.

There is a workaround that works, though: name the *.cmd file explicitly as an alternate NAME for the find_program command. Just as a workaround, it works fine.

find_program is often used in Modules for finding a certain command.
I think it straight forward solution to make CMake support PATHEXT instead of making a copy of Modules.

If using PATHEXT environment is difficult, I suggest to support at lest .com;.exe;.bat;.cmd, which is the default value of PATHEXT:
