A better way is to check the return value of pkg-config. It returns 0
if the package is installed and a non-zero value if it isn't. You can
also use the --exists option to check for a specific library version.
Depending on a non-empty string returned by --cflags or --libs is
unsafe. Pkg-config may return an empty string if no extra options are
needed to compile against a particular library.

Should be good as a first step. There
shouldn't be -Wall.
The next step would be to check for ssl (similar to tls).
If you want, I can push a fix later on, or you can experiment :)
Please go ahead,
Ovidiu. I feel more confident with you handling this stuff ;-)
The problem I have with the websocket module seems to be that while the library is
installed as part
of the system in /usr/lib (not /usr/local/lib) pkg-config doesn't return an answer.
Our scripts seems to
depend on pkg-config always delivering a proper answer if it exists. I suggest we check
if the string
returned by pkg-config is empty and if it is, use LOCALBASE only. That works on my
FreeBSD system.
