Hi guys,
I've a problem regarding pkg-config.
My project uses an external library in order to parse EXIF data. This parsing is optional, so I'd like to use pkg-config to check the presence of the library, and to proceed without it if absent.
I've added in my .pro file these rows:
CONFIG += ... link_pkgconfig
PKGCONFIG += exiv2
and it works.
What I want is to add a define switch to g++ according to the presence of exiv2 library.
I tried to use this code (of course, it's specified after the two rows above):
CHECK_EXIV2 = $$find ( LIBS, ".*exiv2.*" )
!isEmpty( CHECK_EXIV2 ) {
DEFINES += EXIV2
}
but it doesn't work. Looking into Makefile, I can see "-lexiv2" in LIBS variable, but this code fails anyway
How can I solve it?
Thanks so much
Regards,
Tony.
