7.4 Environment variables

GENOM_CPP
Define the C preprocessor program to use. The default is libexec/genom-pcpp. The GENOM_CPP program must recognize -I and -D arguments.
PKG_CONFIG
Define the path to the pkg-config(1) program.pkg-config(1) may be spawned by genom-pcpp for handling the #pragma require directive. The default is to search in the PATH variable.
GENOM_TMPL_PATH
The value of GENOM_TMPL_PATH is a colon-separated list of directories, much like PATH, where GenoM looks for templates. Setting this variable overrides the default search path, but any -t option takes precedence over this variable.
TMPDIR
Path to the directory holding temporary files. Defaults to /tmp.
