I hate it when distros split packages in their own unique and bizarre
ways. "Disk" space is now so cheap, expending human capital to save a
few bytes has a very low return on investment.
Is there a way to detect that the "dev" parts are, or are not,
installed?
SConscript uses CheckPkG to see if libusb-1.0 is installed:
if config.CheckPKG('libusb-1.0'):
That just runs:
pkg-config --exists 'libusb-1.0'
The pkg-config man page says:
"The pkg-config program is used to retrieve information about installed
libraries in the system. It is typically used to compile and link
against one or more libraries. "
Why would pkg-config return true for exists if the package can mot
be "compile and link"?

The orininal questions was the reverse. Can gpsd be build without
libusb being installed. Can you confirm that as well?
