3.1.2. LM_LICENSE_FILE Environment Variable

Intel® and third-party software use the LM_LICENSE_FILE environment variable to specify the locations of license files or license servers. For example, both the Intel® Quartus® Prime software and the Siemens* EDA software use the LM_LICENSE_FILE variable to specify the locations of their licenses.
Note: The time it takes for your development machine to communicate with the license server directly affects compilation time. If your LM_LICENSE_FILE environment variable setting includes paths to many license servers, or if the license server is hosted in a distant locale, you will notice a significant increase in compilation time.

On Linux or UNIX systems, insert a colon (:) after each license file or license server location that you append to the LM_LICENSE_FILE environment variable.

On Windows systems, insert a semicolon (;) after each license file or license server location that you append to the LM_LICENSE FILE environment variable.

Note: When modifying the LM_LICENSE_FILE setting to include the locations of your software licenses, do not remove any existing license locations appended to the variable.
