You are probably using a newer kernel > v4.4.x that does not support cape manager but uses u-boot overlays.
Check out these links for more information:
https://groups.google.com/forum/#!topic/beagleboard/OG1_tts4OcU
Depending on your configuration you should edit the /boot/uEnv.txt file to add the driver.
Try adding something like this:
enable_uboot_overlays=1
dtb_overlay=/lib/firmware/hcsr04-00A0.dtbo
and ignore the make install error related to missing cape manager.

Hello,
Please I have the same problem I get the following error when I run make install command
bin/sh: 1: cannot create /sys/devices/bone_capemgr.9/slots: Directory nonexistent
And I tried the change on /boot/uEnv.txt file solution, but the problem is not solved
I tried also to run ./hcsr04 command and I get the following errors
>> Initializing PRU
>> PRU open failed
PLease is there any other solution?
debian@beaglebone:~/hcsr04-master$ make install
cp hcsr04-00A0.dtbo /lib/firmware
echo hcsr04 > /sys/devices/bone_capemgr.9/slots
/bin/sh: 1: cannot create /sys/devices/bone_capemgr.9/slots: Directory nonexistent
Makefile:25: recipe for target 'install' failed
make: *** [install] Error 2
from hcsr04.
