[Bug 1469708] Re: cmake does not find wait.h using the "check_include_files"-statement

[Lazalatin]

** Description changed:

  Ubuntu Version: 15.04
  CMake Version: 3.0.2
  
- 
- This specific issue was only caused by finding the (existing) wait.h header file while building a CMakeLists file
+ This specific issue was only caused by finding the (existing) wait.h
+ header file while building a CMakeLists.txt file
  
  Whilst using this statement causes no errors on Arch or Debian Linux, it
  seems that under Ubuntu existing files are totally ignored.
  
  Using the following checks only caused an error message on wait.h:
  
+ Include(CheckIncludeFiles)
+ 
+ ...
+ 
  check_include_files( wait.h HAVE_SYS_WAIT_H )
  if( NOT HAVE_SYS_WAIT_H )
- 	message( FATAL_ERROR "Did not find sys/wait.h" )
+  message( FATAL_ERROR "Did not find sys/wait.h" )
  endif()
  
  check_include_files( unistd.h HAVE_UNISTD_H )
  if( NOT HAVE_UNISTD_H )
- 	message( FATAL_ERROR "Did not find unistd.h" )
+  message( FATAL_ERROR "Did not find unistd.h" )
  endif()
  
  While unistd.h is detected, the wait.h header-file is not. (Although it
  exists in /usr/include)
