Building Qt 5 seems to ignore PKG_CONFIG_PATH
-
I'm trying to build Qt 5 on Linux against some other libraries not in the standard path.
For example, I build some dependencies and /tmp/xcb. I set PKG_CONFIG_PATH to /tmp/xcb/lib/pkgconfig. But Qt's "configure" always bombs with
"ERROR: Feature "xcb" was enabled, but the pre-condition 'libs.xcb failed."
When I look at config.log, it shows that pkg-config did not find xcb. But from the command prompt it finds it just fine when PKG_CONFIG_PATH is set.
So what gives? Does 'configure' blank out and ignore that env var?
Any suggestions?

Hi and welcome to devnet,
Which version of Qt 5 are you trying to build ?
In between you can add the library and include path using the -L and -I options to configure. Just one thing to take into account, you need a space between the option and the path in this case.

version 5.8.0
I tried -L and -I with "configure", but still saw the same error in config.log stating that when it tries to compile the xcb.c test it cannot find <xcb/xcb.h>
I see in config.log that it uses pkg-config to try to find xcb, but according to the log pkg-config doesn't see it.

Indeed it does.
So you go it to compile as you wanted ?
