To compile the LM-X SDK from a command line:
Step 1. Make sure the config directory includes the license file.Copy your LM-X-SDK lmx.lic file to the config directory.
Note: If you are upgrading LM-X, remember about copying your LM-X security configuration file from a previous LM-X installation to the config directory. (In LM-X SDK versions older than 4.2, security_config.lmx file was named after your vendorname.lmx.)
Step 2. From the root directory of the LM-X distribution, run make.
