Hi I have big problem with rmabick installation on CenotOS 5.5 I installed ImageMagick from source and tes it from line command and works ok. What is wrong. Please somebody help me !

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more

I reported the above errors when compiling mlpack with QNX.And I have compiled necessary dependencies like armadillo and boost. I would like to ask why this error is reported? And what should I do?
I am compiling mlpack using QNX.Keep reporting the following errors:

I have added the following to CMakeLists.txt:

Does anyone know what should I do ?
You need to ensure that you've added the QNX build toolchain to your environment. QNX provides the 'qnxsdp-env.sh' shell script (or qnx-sdp-env.bat for Windows) to set up the toolchain. This will set all appropriate environment variables. Run this script before trying to use any other build commands such as cmake, make, qcc, etc.
Inferring from your example that you're using QNX 7.0 on a Linux host, try:
$ source /data/QNX/qnxsdp-env.sh
$ cmake
Note that source is important: it instructs the shell to run the script such that it can modify the current shell environment, rather than launching it in a subshell. If you run the script without source, the script will have no effect.

I'm trying to run the sample dnn program from opencv's website for object detection
Here's what my CMakeLists.txt looks like:
project( IOT_MINI )
set(CMAKE_CXX_STANDARD 14)
SET(OpenCV DIR /usr/local/include/opencv4)
find_package(OpenCV 4 REQUIRED)
INCLUDE_DIRECTORIES(${OpenCV_INCLUDE_DIRS})
message(STATUS "OpenCV library status:")
message(STATUS " config: ${OpenCV_DIR}")
message(STATUS " version: ${OpenCV_VERSION}")
message(STATUS " libraries: ${OpenCV_LIBS}")
message(STATUS " include path: ${OpenCV_INCLUDE_DIRS}")
add_executable( Dog_detector Dog_detector.cpp )
target_link_libraries( Dog_detector ${OpenCV_LIBS} )
I can successfully find OpenCv 4. cmake .. runs successfully. But while make it links(?) to conda environment.
I don't know how to reproduce this exactly since I have ROS, conda and opencv installed and I don't know what exactly is causing the problem.

You can add that libippicv.a library as simple object file to linker command line at the end. Or, treat it as a library "cc ..... -L 3rdparty/ippicv/unpack/ippicv_lnx/lib/ia32 -lippicv" so as ordinary libraries are used while linking.
