How to link locally built third party libraries

[Jim-215-Fisher]

I was trying to use fpm to build a Fortran project. The project requires several locally built libraries. How do I specify the paths and libraries as well as mod files in fpm.toml?

Hi @Jim-215-Fisher,

See this section of the manifest reference for linking.

To use external mod files (that is, not the ones from fpm package dependencies), see this section.

fpm will still need to know where to find your external mod files, and there are two ways to do it:

1. Copy or symlink them into the include/ directory in the root of your fpm project. This directory is added to the include and modules path by default.
2. Specify a path on the command line, i.e. fpm build --flag '-I/path/to/mod/files'.
