Compile Static executable with CMAKE

I am trying to build static executable but having no success in building up. It was working fine before adding following lines:

SET(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
SET(BUILD_SHARED_LIBRARIES OFF)
SET(CMAKE_EXE_LINKER_FLAGS "-static")

I want to convert it into static executable. Any help or suggestions?

Here is my cmake Code : 

cmake_minimum_required(VERSION 3.5)

set(CMAKE_CXX_STANDARD 11)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -g -Werror -lpthread")
SET(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
SET(BUILD_SHARED_LIBRARIES OFF)
SET(CMAKE_EXE_LINKER_FLAGS "-static")

                                      pthread)

I tried merging steps from the link, but not working and getting following error:

/usr/bin/ld: attempted static link of dynamic object `/usr/lib/x86_64-linux-gnu/libGLU.so' collect2: error: ld returned 1 exit status src/CMakeFiles/wwest-outreach-app.out.dir/build.make:774: recipe for target 'bin/wwest-outreach-app.out' failed make[2]: * [bin/wwest-outreach-app.out] Error 1 CMakeFiles/Makefile2:85: recipe for target 'src/CMakeFiles/wwest-outreach-app.out.dir/all' failed make[1]: * [src/CMakeFiles/wwest-outreach-app.out.dir/all] Error 2 Makefile:83: recipe for target 'all' failed make: *** [all] Error 2

Here is the link that I tried following: Compiling a static executable with CMake

Note: I added following line and it compiled but not statically as I still cant open the output file (.out) on other linux machines.

set(CMAKE_EXE_LINKER_FLAGS "-static-libgcc -static-libstdc++")

Can you locate libGLU.a on your system? The linker cannot link a dynamic lib (libGLU.so) to a statically built program.

If you can find libGLU.a on your system, make sure it is available in CMAKE_LIBRARY_PATH.

If you /still/ have problems with cmake picking the dynamic library over the static archive, try adding this to your CMakeLists.txt above the find command:

set(CMAKE_FIND_LIBRARY_SUFFIXES .a ${CMAKE_FIND_LIBRARY_SUFFIXES})

And last but not least, a reminder to clear your cmake cache so it isn't hanging onto libGLU.so.
