2 years ago When you cmake librealsense, you have to mkdir a build directory in the librealsense directory.
Move in librealsense/build and :
$ cmake ../ -DCMAKE_PREFIX_PATH=~/apriltag
To tell cmake the path to librealsense directory.
In my case, it doesn't work.
When I try :
root@4f8b0335d5f8:/librealsense/examples/pose-apriltag# g++ -o rs-pose-apriltag rs-pose-apriltag.cpp
It says :
`rs-pose-apriltag.cpp:12:22: fatal error: apriltag.h: No such file or directory
include "apriltag.h"
^compilation terminated. `
EDIT : it is not necessary to compile it since it is already done.
I use this cmake :
$ cmake ../ -DCMAKE_PREFIX_PATH=~/apriltag -DCMAKE_BUILD_TYPE=release -DFORCE_RSUSB_BACKEND=true -DBUILD_EXAMPLES=true
Just run the command, like :
root@4f8b0335d5f8:/# rs-pose-apriltag
It is working for me with all the librealsense examples.
EDIT 2 : if you want to compile your own code using librealsense, apriltag and probably other libraries, you have to use cmake.

Issue Description
In "Installing Apriltag library in a local directory" step, I unpack the github file in "~/apriltag" and create a new folder "apriltag-3.1.1" in "~/apriltag" , then I create another folder "apriltag-build" in "~/apriltag", I done the "cmake" and "make install" in "apriltag-build", but when I move on, it tells me to run the command "cmake -DCMAKE_PREFIX_PATH=~/apriltag", I do not know the "" means, so can anyone tell me what is the "" means and I should run this command in which folder, thanks.
