I have been trying on and off for the past year to import the NLopt library into my work. I have been unsuccessful, and I am desperate for help.
Here is some of my CMAKE file

You can see that I've commented out a number of attempts at getting this imported. CMake does not throw any errors. However, if I try building the project, I get:

The library to link with is likely not in the include directory with the header files. It's more likely they're in a lib directory:

I am using the experimental GLM hash features in a CMake project.
Everything works fine unless the project is generated by Clion.
When building the Clion generated project GLM raises the error "GLM_GTX_hash requires C++11 standard library support" (see CMake logs) although C++11 is enabled.
Building the same, clion generated, project from a terminal fails with the same error.
However, when generating and building the project with cmake 'manually' (without Clion even knowing about it) everything works fine. As expected.
GLM is not directly included in the CMakeList. GLFW includes/imports it.
Example CMakeLists.txt
(...)
set(CMAKE_CXX_STANDARD 11)
add_executable(Test main.cpp)
(...)
add_subdirectory("glfw" ${CMAKE_CURRENT_BINARY_DIR}/glfw)

#define GLM_ENABLE_EXPERIMENTAL
#include <glm/gtx/hash.hpp>

Now I am actually curious about rather I messed up somewhere or if it is simply a bug. And if so, where should I report it?
[Clion/Jetbrains?, GLM?, GLFW?, CMake?]
Thanks in advance
Update
I am using the latest available (for me) builds:
CMake version: 3.14.4
Operating System: Arch Linux 5.0.18-1 x86_64 GNU/Linux
GLFW version/commit: d834f01c
GLM version/commit: fce2abd0
Clion: 2019.1.3
Clion EAP: 2019.2 EAP
Final update / 'Solution'
I just discovered that the problem is Clang, not Clion or anything else.
Clion simply defaulted to Clang (instead of GCC).
There are bug reports for GLM and Clang already existing (with potential fixes!):
https://github.com/g-truc/glm/issues/620
https://github.com/g-truc/glm/issues/646
Thank you very much everyone ~
To resolve this error I tried to add extra module opencv-contrib-master from https://github.com/opencv/opencv_contrib.git I followed the steps given in the readme.md file but while running 'make' I am getting the following output:

Somewhere it was told that there may be problem in gcc version but I updated gcc version but no success. I am using gcc of version 4.9.4 and ubuntu of version 14.04.1. Before 'make' step I ran:
cmake -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules /usr/local .. -DWITH_IPP=OFF -DWITH_OPENGL=ON -DWITH_QT=ON -DBUILD_EXAMPLES=ON
I approached many resources but no results. Any kind of help is appreciable.
Did you tried prepending the command with sudo?
The problem is that xfeatures2d was not being exported from opencv-contrib module. So, when I was running 'make' command it was not able to add that module to opencv build module.
I ran the following command followed by make command:
export xfeatures2d=/path/to/opencv_contrib/modules/
It worked for me.
I've extracted official llvm/clang sources for 3.7 release, did some minor patching (NSGetEnviron()), configured and build for iOS with cmake:
cmake ../llvm_37_ios \

Did i miss something or it's clang configuration bug?
libclang is built as a shared library by default because it simplifies consumption from other languages such as Python using FFI or similar mechanisms.
To build a static library use LIBCLANG_BUILD_STATIC CMake option defined in clang/tools/libclang/CMakeLists.txt:
option(LIBCLANG_BUILD_STATIC
"Build libclang as a static library (in addition to a shared one)" OFF)
You can use it as follows:
cmake -DLIBCLANG_BUILD_STATIC=ON ...

I don't know how to deal with this problem.
Cygwin's gnulib does not provide execinfo.h, possibly due to compatibility issues with the underlying (Windows) system.
From the gnulib documentation:
This header file is missing on some platforms: Mac OS X 10.3, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin, mingw, MSVC 9, Interix 3.5, BeOS.
You may want to try a WinAPI function like CaptureStackBackTrace instead.

what can i do ?
You can start by reading the error message:

That's probably not your problem, but one idea is to try to install OpenCV 32-bits:
brew install opencv --32-bit
And if that doesn't work:
please report the bug:

You can always download OpenCV source code and compile it yourself. It's what I did on Mac OS X.
