Compile only. Default: current directory
GFortran option: -I
Instruct the compiler to search the specified path(s) for Fortran INCLUDE files after searching the current directory and to search for ‘.mod’ files when previously compiled modules are required by a USE statement. Separate multiple search paths with a semicolon, not spaces. If a space appears as part of a pathname, the entire path must be enclosed in quotes.
In this example, the compiler first searches the current directory, then searches ..\project2\includes and finally ..\project3\includes for INCLUDE files specified in the source file DEMO.F90
