We will create project and find some substring (EXTERNAL)

CMakeLists.txt:
================================================
cmake_minimum_required (VERSION 2.6)
project (test0)

set(SOURCES test0.c)

add_executable (test0 ${SOURCES})
================================================

test0.c
================================================
int main(int argc, char** argv) {
      return 0;
}
================================================

Scenario:
- Create source based project (select Automatic mode)
- Call Context menu on project node and select Find

1) default search display 1 item only (configurations.xml)
2) select folder in Scope field (a lot of mouse clicks). 4 matches in 3 files (CMakeCache.txt, build.make and configurations.xml)
3) select Grep tab and IDE found 6 matches (NetBeans duplicates all items)

P.S. Also via grep I can find in .o files, but "Default Search" ignores these files
