I'm trying to do a static compile of a C++ project using CMake, but it seems to still be linking dynamically. I'm new to CMake so I'm not entirely sure of how everything works.
This is my project root directory's CMakeLists.txt:
cmake_minimum_required(VERSION 3.5)
set(CMAKE_CXX_STANDARD 11)
SET(CMAKE_LINK_SEARCH_START_STATIC TRUE)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -g -Werror")
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
#project(wwest-outreach-app.out)
project(WWEST LANGUAGES CXX)
add_subdirectory(src)
add_subdirectory(test)
include_directories(include)
file(COPY data DESTINATION bin/)
/src/'s CMakeLists:
cmake_minimum_required(VERSION 3.5)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -g -Werror -lpthread -std=c++0x -lglut")
SET(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
SET(BUILD_SHARED_LIBRARIES OFF)
SET(CMAKE_EXE_LINKER_FLAGS "-static -static-libgcc -static-libstdc++")

I added the -static flags as per answers in similar questions like CMake and Static Linking and Compiling a static executable with CMake , but now I'm getting errors:
/usr/bin/ld: attempted static link of dynamic object `/usr/lib/x86_64-linux-gnu/libGLU.so'
if I try adding
add_library(libGLU /usr/lib/x86_64-linux-gnu/libGLU.a)
then I get
CMake Error: Cannot determine link language for target "libGLU".
CMake Error: CMake can not determine linker language for target: libGLU
Then, I put set_target_properties(${PROJECT_NAME} PROPERTIES LINKER_LANGUAGE CXX) after add_executable only to get the above link language error for cmake ./ and and make[2]: *** No rule to make target 'src/CMakeFiles/libGLU.dir/build'. for make.
Super lost and confused. Help please?
EDIT: I updated my question and my Cmake code to reflect my efforts to fix this and to be more specific with the error I'm getting.
EDIT 2: After trying some suggestions I was given I'm now getting this error:
