What would be the general algorithm I should follow to debug issues such as this one?

Error while building/deploying project jumper-qt (kit: Desktop)
When executing step "CMake Build"
23:28:15: Elapsed time: 00:04.
The example project use both Qt (Quick 2) and Magnum, both of these libraries make extensive use of OpenGL. When I start example projects for them separately, they both work well and build with no error. When I try to marry them, it falls a part.
So what would be a procedure to follow in this case? How do I find out out why these (glFlush) declarations are missing? I tried adding find_package(OpenGL.... to my project, with no success. I'm interested in the process of finding out what's the problem, not in a solution to this particular problem.
Thank you SO
UPDATE: CMake files here https://gist.github.com/skrat/c5b20d6753e6476a4a0d60227cb73cda
Before including Magnum, I had the same project, where I included find_package(OpenGL... and was able to use raw OpenGL calls successfully. In a separate Magnum only project, I don't have to find package OpenGL and all is fine, I assume Magnum's CMake files do the hard work.
Also this might be relevant https://github.com/mosra/magnum-bootstrap/blob/base-qt/modules/FindMagnum.cmake

The errors I get are that isinf and isnan don't belong to the std namespace. My understanding is that this is true if math.h is being imported, but not if cmath.h is being imported. However, I can see in the last compile line that std=c++11, and when I check test_gpu.cu, I see that cmath is being imported:
#include <cmath>
#include <random>
#include <tuple>
#include <vector>
#include <iostream>
At this point, I don't really know how to proceed. Any thoughts or suggestions would really help....

I am attempting to install warp-ctc from https://github.com/baidu-research/warp-ctc
I'm trying to create simple lib for the R with statically linked boost.
CMakeLists.txt
cmake_minimum_required(VERSION 3.3)
project(TheRPath)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -Wall -Werror")

include_directories("/usr/share/R/include")
set(SOURCE_FILES Path.cpp Path.h)
add_library(therpath SHARED ${SOURCE_FILES})
target_link_libraries(therpath ${Boost_LIBRARIES})
Interpreter gives me an error when I'm trying to load shared object.
> dyn.load("libtherpath.so")
Error in dyn.load("libtherpath.so") :
unable to load shared object 'libtherpath.so':
libtherpath.so: undefined symbol: _ZN5boost6system15system_categoryEv
I have the following code:
Path.h
#ifndef PATH_H
#define PATH_H
#include <Rinternals.h>
extern "C" SEXP foo(SEXP snapshotPath);
#endif // PATH_H
Path.cpp
#include <string>
#include <boost/filesystem.hpp>
#include "Path.h"
extern "C" SEXP foo(SEXP snapshotPath) {
std::string path(R_CHAR(STRING_ELT(snapshotPath, 0)));
std::cerr << path << boost::filesystem::path::preferred_separator << "file.txt" << std::endl;
return R_NilValue;
}
Could you tell me what I'm doing wrong?

libboost_filesystem depends on libboost_system. You need to add it to your CMakeLists.txt:
find_package(Boost REQUIRED COMPONENTS filesystem system)
Note I omitted the optional Boost version number, because you probably don't really need or want to specify it. But you can if you feel compelled.

I have Cmake installed (sudo apt-get cmake), Gcc (4.6.3) and OpenCV.
How can I solve the problem?
Raspberry Pi is ARM, -msse* does it apply. Based on the CMakeFile, they detect ARM and disabled SSE flags. Maybe it is not working for you, perhaps due to a different cmake version
Try changing this
IF(DEFINED ENV{ARM_ARCHITECTURE})
to
IF(DEFINED $ENV{ARM_ARCHITECTURE})
This is line 34 in CMakeLists.txt
If the fix does not work, then you could manually enable ARM specified flags by editing CMakeLists.txt
Remove this:
IF(DEFINED ENV{ARM_ARCHITECTURE})
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mfpu=neon -march=armv7-a")
ELSE()
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mmmx -msse -msse -msse2 -msse3 -mssse3")
ENDIF()
and replace with this
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mfpu=neon -march=armv7-a")
Maybe report an issue on github and tell the authors about it.
EDIT: you want to do these edits in https://github.com/uzh-rpg/fast/blob/master/CMakeLists.txt
Also try setting export ARM_ARCHITECTURE=1 before compiling
This is my very first post here. I am trying to compile RGBdemo to test its reconstruction capabilities with kinect.
I have followed these instructions
RGBdemo compiling instructions
I was able to follow all the instructions more or less consistently but I stomp at the ending (compiling RGBdemo 0.7). Here is the make code.

I have not much experience in compiling programs although I have some programming skills.
I have searched extensively how to solve this issue searching for the errors
"reference to symbol 'glOrtho'" and "adding symbols: DSO missing from command line" but I can't find a decent solution that helped me.
For example this case
Linker error : undefined reference to symbol 'glOrtho'
states that I should link an OpenGL library to a certain file. In my case I think it should be main.cpp but I am unable to find it :-(.
Any help is much appreciated.
Update

I will try to find how to correct those directories but I would really apreciate some help on this. Please, I am doing this a bit by trial and error and I know this is not the right way to go. I am not an expert on cmake compilation.
I had to remove and reinstall OpenCV 2.3.1 with these instructions
http://www.ozbotz.org/opencv-installation-2-3-1/
And after some magic...voilá. It works. I hope that this tips can somehow help anyone.
