Mostly writing this down for me, next time we need to run Open ZWave and try to build the latest version:

Download libmicrohttpd
Gunzip & untar it
cd libmicrohttpd
./configure
make
make install

Download and build the open-zwave library

mkdir /opt/ozw
cd /opt/ozw
git clone https://github.com/OpenZWave/open-zwave.git
cd open-zwave-master
make

Find error in build that says you don’t have libudev.h, install systemd-devel (dnf install systemd-devel) & try that make again.

Download open-zwave-control-panel
cd /opt/ozw
git clone https://github.com/OpenZWave/open-zwave-control-panel.git
cd open-zwave-control-panel-master

Open the Makefile and find the following line:
OPENZWAVE := ../

Change it to:
OPENZWAVE := ../open-zwave-master

Then find the section that says:
# for Linux uncomment out next three lines
LIBZWAVE := $(wildcard $(OPENZWAVE)/*.a)
#LIBUSB := -ludev
#LIBS := $(LIBZWAVE) $(GNUTLS) $(LIBMICROHTTPD) -pthread $(LIBUSB) -lresolv

# for Mac OS X comment out above 2 lines and uncomment next 5 lines
#ARCH := -arch i386 -arch x86_64
#CFLAGS += $(ARCH)
#LIBZWAVE := $(wildcard $(OPENZWAVE)/cpp/lib/mac/*.a)
LIBUSB := -framework IOKit -framework CoreFoundation
LIBS := $(LIBZWAVE) $(GNUTLS) $(LIBMICROHTTPD) -pthread $(LIBUSB) $(ARCH) -lresolv

And switch it around to be Linux … the Makefile becomes:
# for Linux uncomment out next three lines
LIBZWAVE := $(wildcard $(OPENZWAVE)/*.a)
LIBUSB := -ludev
LIBS := $(LIBZWAVE) $(GNUTLS) $(LIBMICROHTTPD) -pthread $(LIBUSB) -lresolv

# for Mac OS X comment out above 2 lines and uncomment next 5 lines
#ARCH := -arch i386 -arch x86_64
#CFLAGS += $(ARCH)
#LIBZWAVE := $(wildcard $(OPENZWAVE)/cpp/lib/mac/*.a)
#LIBUSB := -framework IOKit -framework CoreFoundation
#LIBS := $(LIBZWAVE) $(GNUTLS) $(LIBMICROHTTPD) -pthread $(LIBUSB) $(ARCH) -lresolv

ln -sd ../open-zwave/config
make

Then you can run it:
./ozwcp -p 8889

./ozwcp: error while loading shared libraries: libmicrohttpd.so.12: cannot open shared object file: No such file or directory

strace it (strace ./ozwcp -p 8889)

Huh … not looking in the right place. I’m sure there’s a right way to sort this, but we’re using Open ZWave for a couple of minutes to test some ZWave security stuff. Not worth the time:

ln -s /usr/local/lib/libmicrohttpd.so.12.41.0 /usr/lib64/libmicrohttpd.so.12

Try again (./ozwcp -p 8889). Voila, “2017-04-17 20:35:05.223 Always, OpenZwave Version 1.4.0 Starting Up”. Use your browser to hit http://<ipaddress>:8888 to access the Open ZWave Control Panel.
