[CMake] ExternalProject_Add fails with gcc-4.9.3

[T.Sariyski]

cmake version 3.4.3

Hi,

I have ExternalProject_Add (attached), which works with gcc-4.4.7, but fails
with gcc-4.9.3:

...
...
[100%] Performing build step for 'ep_netcdf'
	CMake Error at
/scratch/tesari/build/cee/gnu.dbg/netcdf/src/ep_netcdf-stamp/ep_netcdf-build
-DEBUG.cmake:16 (message):
  	Command failed: 2
  	 'make'
 	 See also
 
/scratch/tesari/build/cee/gnu.dbg/netcdf/src/ep_netcdf-stamp/ep_netcdf-build
-*.log (attached).

If I execute configure and make, as defined in  ${CONFIGURE_COMMAND}, it
works.

What is the meaning of  "Command failed: 2 'make'" error message, and how
should I track it down? Any help is highly appreciated.

Thanks in advance,
Ted
