"using this command to avoid manually listing all instantiations.\n"
"It is tempting to use this command to avoid writing the list of "
"source files for a library or executable target. While this seems "
"to work, there is no way for CMake to generate a build system that "
"knows when a new source file has been added. Normally the "
"generated build system knows when it needs to rerun CMake because "
"the CMakeLists.txt file is modified to add a new source. When the "
"source is just added to the directory without modifying this file, "
"one would have to manually rerun CMake to generate a build system "
"incorporating the new file.";
