2 #! Compile code snippets from a given directory
4 #! This CMake function globs all files called \e main.cpp in the
5 #! directory given by <code>snippet_path</code> and creates
6 #! an executable for each found main.cpp.
8 #! If a \e files.cmake file exists in the same directory where a
9 #! main.cpp file was found, it is included. This function assumes
10 #! that the files.cmake file sets a list named \e snippet_src_files
11 #! containing a list of files which should be compiled into the
12 #! executable. If no files.cmake file is found, all files in the
13 #! directory are compiled into the executable.
15 #! This function uses all additionally passed arguments as link
16 #! dependencies for the created executable.
