 # Script to collect sources and put them into CMakeLists.txt file. It substitutes section 
 # between magic strings with a generated list of sources.
 # Magic strings are: ^#sources_begin, ^#sources_end (^ denotes beginning of the line).
 #
 # usage: awk [-v src_dirs="dir1 dir2 ..."] [-v src_files="pattern1;pattern2;..."] [-v cmake_var="VAR"] -f cmakesrcs.awk CMakeList.txt
 # example: awk -v src_dirs="src/dir1 src/dir2" -v src_files="*.cxx;*.c" -v cmake_var="SOURCES" -f cmakesrcs.awk CMakeList.txt
 #
 # parameters: 
 # find - find program.
 # src_dirs - where to look for sources (default: "*").
 # cmake_var - cmake sources variable name (default: "SRCS").
 # src_files - list of source file patterns separated by a semicolon (default: "*.cpp;*.c").
 #
 # required tools: awk, find (findutils).
 #
 # Note on MS Windows: find shipped with findutils may be shadowed by Windows' find.exe,  
 # residing in Windows/system32 folder. Windows find.exe is a different tool and it has to
 # be moved behind findutils find in script search path. Alternatively you can pass find 
 # parameter to the script pointing to findutils find binary.
