MinGW must be installed into C:\MinGW
C:\MinGW\bin;C:\MinGW\msys\1.0\bin should be added to %Path%
CLang should be downloaded from http://llvm.org/releases/download.html and installed into D:\LLVM

==========================================================================================
Problem 1:
- Add D:\LLVM\bin into "Tool Collection"
==> IDE selects "CLang" family
- Create and build Welcome
==>
cd 'C:\Users\sova\Documents\NetBeansProjects\Welcome_1'
C:\MinGW\msys\1.0\bin\make.exe -f Makefile CONF=Debug
"/c/Users/sova/Documents/NetBeansProjects/Welcome_1/"C:/MinGW/msys/1.0/bin/make.exe"" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
/bin/sh: /c/Users/sova/Documents/NetBeansProjects/Welcome_1/C:/MinGW/msys/1.0/bin/make.exe: No such file or directory
make.exe": *** [.build-impl] Error 127

BUILD FAILED (exit value 2, total time: 673ms)
==========================================================================================
Problem 2 (NetBeans can find Cygwin in Windows registry):
- Add D:\LLVM\bin into "Tool Collection", but MinGW family should be selected
- Create and build Welcome
