Jmake compiling the current directory C + + Single file specifies the file to add options

The base version of Jmake is to generate a single-file-compilation command for all C + + files under the current folder, and the Jmake command is not optional.

Now the improvement is to be able to add some options when entering the command jmake, '-' the options that begin with are added to the build command for each compiled single file, and the other option is to specify the source file to be compiled. Of course, if the source file is not specified, all the. c,.cc,.cpp files are compiled separately.

The code is as follows:
