If the sha1.pc file isn't available, this causes an error and the build
fails:

checking for LIBSHA1... configure: error: Package requirements (sha1) were not met:

No package 'sha1' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LIBSHA1_CFLAGS
and LIBSHA1_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
