Matt Huszagh 9320c69ecb kicad: set default footprint, symbol library and package locations
Previously, these library locations were set absolutely. This
prevented overriding their locations with environment variables. Now,
setting the corresponding environment variable will override the
setting in the environment wrapper. For instance, I can set

KISYSMOD=/some/path/to/footprints

and this will be used as my footprint library instead of the default
footprint library in the nix store. This feature is particularly
useful for having kicad libraries which are writable.

# The `srcs` parameter can be used to override the kicad source code
# and all libraries (including i18n), which are otherwise inaccessible
# to overlays since most of the kicad build expression has been
# refactored into base.nix, most of the library build expressions have
# been refactored into libraries.nix, and most the i18n build
# expression has been refactored into i18n.nix. Overrides are only
# applied when building `kicad-unstable`. The `srcs` parameter has no
# effect for stable `kicad`. `srcs` takes an attribute set in which
# any of the following attributes are meaningful (though none are
# mandatory): "kicad", "kicadVersion", "i18n", "symbols", "templates",
# "footprints", "packages3d", and "libVersion". "kicadVersion" and
# "libVersion" should be set to a string with the desired value for
# the version attribute in kicad's `mkDerivation` and the version
# attribute in any of the library's or i18n's `mkDerivation`,
# respectively. "kicad", "i18n", "symbols", "templates", "footprints",
# and "packages3d" should be set to an appropriate fetcher (e.g.,
# `fetchFromGitLab`). So, for example, a possible overlay for kicad
# is:
#
# final: prev:
# {
# kicad-unstable = (prev.kicad-unstable.override {
# srcs = {
# kicadVersion = "2020-10-08";
# kicad = prev.fetchFromGitLab {
# group = "kicad";
# owner = "code";
# repo = "kicad";
# rev = "fd22fe8e374ce71d57e9f683ba996651aa69fa4e";
# sha256 = "sha256-F8qugru/jU3DgZSpQXQhRGNFSk0ybFRkpyWb7HAGBdc=";
# };
# };
# });
# }
