Bitbake depends AAA packet, it will rdepends AAA-dev - bitbake

Question

I add depends packet to a exist .bb file, such as add DPENDS="AAA" line to .bb file, when I compile the .bb file, it failed for XXX rdepends on AAA-dev [dev-deps], and I search google, all the answer almost is add line INSANE_SKIP_${PN} += "dev-deps" or RDEPENDS_${PN}_remove = "AAA-dev" to .bb file.
But my question is why? why one packet depend AAA packet, it should also RDPENDS AAA-dev, is there any other answer to fix this problem
The bb source file is:
inherit autotools qcommon

I add a DEPENDS on onenet pkg

The sanity check documentation explains this:
dev-deps: Checks that all packages except -dev or -staticdev packages
do not depend on -dev packages, which would be a packaging bug.
It's telling you that in your current recipe "XXX" runtime-depends on "AAA-dev" and that this is a normally an error. You need to find out how/why this dependency is added before you can decide what the correct solution is.
Based on the added recipes: The issue seems to be that onenet build produces an unversioned ".so" file. This is typically a mistake (the actual library file should be e.g. "libmqtt.so.1.1" and the unversioned file should just be a symlink to the versioned one). I'm very surprised that you are not getting a fatal error on this issue when you build onenet. Are you suppressing the QA error for this?
Since you've managed to build onenet somehow, you now probably have a onenet-dev package that erroneously contains the actual library: The build system notices this during atfwd-daemon build, adds a runtime dependency to onenet-dev (because that's where the library is) and then the QA error triggers because normal packages should not depend on -dev packages.
Possible fixes:
Either fix the onenet build system so it produces a versioned library, or
Force the .so file to be packaged into the actual onenet package instead of onenet-dev, like this:
FILES_${PN}-dev = "${includedir}/"
FILES_${PN} += "${libdir}/libmqtt.so"
A bonus suggestion: Using directory variables instead of paths like /usr/include and /usr/lib (like I did above) is a good "Best Practice".
