Missing headers in /usr/inlcude for software developers

Thank you Ross.
Everything went fine with makefile. It works in yocto and from cl
Now another issue arise. The software guys will need the headers and when I "populated" sdk they were not in the rootfs. The symbolic links also were not there. The symlink (so.0) and the library is present in the image rootfs. Here is my recipe libanybus-m40.so_0.0.1.bb:
DESCRIPTION = "Anybus M40 Library"
LICENSE = "GPLv2"
LIC_FILES_CHKSUM = "file://${THISDIR}/files/LICENSE;md5=5959e502cb44bafc53b2cc9400e3d4cd"
PR = "r0"
SRC_URI = "git:///home/w23698/projects/anybus/Generic;branch=anybus-lib-0.0.1"
SRCREV = "8594b81241e9538d2ad4d01041e30d97a20b5a43"
S = "${WORKDIR}/git"
PACKAGES = "${PN} ${PN}-dev ${PN}-dbg"
DEPENDS = "libgpiod"

# This is to satisfy yocto QA
TARGET_CC_ARCH += "${LDFLAGS}"

do_compile() {
oe_runmake
}

do_install() {
install -d ${D}${libdir}
install -m 0644 ${PN}.${PV} ${D}${libdir}
}
Obvously I am missing something else....
Cordially

No, you just need to write your makefile correctly. libgpiod has a pkg-config file, so instead of hard-coding paths like /usr/lib (because you don't know that's where it is installed) just use pkg-config to get the flag:

gcc $(pkg-config --cflags --libs libgpiod) ...

OK but. I can use SDKTARGETSYSROOT in my makefile but then it will fail in yocto...So I can't have one makefile for yocto and command line build...I found one tread for similar issue and I will take a look in poky/meta/conf/bitbake.conf tomorrow.

^ don't do that. That's not where the libraries are.

Headers and symlinks for what recipe? This one?

Checksum a file in the source tree.

Redundant, you can remove.

Better to fix your makefile so it doesn't override LDFLAGS
assignments: your makefile is what is broken here.

That's the default, you can remove this.

You're not installing the headers or library symlinks, which is why
they're not in the SDK.

I suggest you move from raw makefiles to a build utility such as
autotools, cmake, or meson.
