DevCPP just calls make.exe which he founds available in enviroment
using either default makefile (the one that DevCpp generated) or
Makefile specified by user (for example the one that I write by hand,
or cmake generates.) I tried setting this first to make.exe one that
came bundled with DevCPP (and is also installed by MinGW installer
from MinGW site) Didn't work. Uninstalled DevCpp and tried clean
install of MinGW v 3.1.0-1 with GNU Make v3.80.0-3 didn't work.
MSYS (fresh install) Same result. Then I tried running from MSYS shell
(I think it is zsh ported to win32) and got the same result. Make
error message is a bit diferent,  but that's because of shell used:

$ make
Building dependencies. cmake.depends...
Building object file hello.o...
/bin/sh: o: command not found
Building executable c:/Temp/hello.exe...
/bin/sh: hello.o: command not found
make[1]: *** [c:/Temp/hello.exe] Error 127
make: *** [default_target] Error 2

Well, I mentioned DevCPP here because I thought there might be some
diference in MinGW and compiler that is bundled with DevCPP and that I
don't know about, but someone else is familiar with . But DevCPP is
just on top of it and it inherits compiler setings from enviroment if
there is no compiler within it's install directory (ie. if I have gcc
in my path, no matter where it is, DevCpp will use it, as long as gcc
knows where to find includes/libs. Same goes for make. DevCPP captures
gcc/make output and parses it, but that's all. The only requirement
from it is that Makefile give to it must contain "all" target. Anyway,
I didn't even test it much with cmake generated Makefiles, after the
first failure, because problem was obviously related to make/cmake.

Each time I cleaned directory completely (only hello.cpp hello.h and
CMakeLists.txt were left in it). Each time cmake GUI was not able to
configure, and cmd line version configured without errors, but then
make failed.

What it looks like to me is that somehow compiler comand doesn't get
called/executed for the given target:

/bin/sh: o: command not found
/bin/sh: hello.o: command not found

or:

process_begin: CreateProcess((null), o hello.o -c C:/Temp/hello.cpp, ...) failed
CreateProcess((null), hello.o -o C:/Temp/hello.exe, ...) failed

But I can't figure out why...
