Hi everyone,

 

I am trying to get an OpenGL project working with CLion on windows but I am having some serious issues with Cmake :( I am using 3 different libraries: GLM, GLEW, GLFW and SOIL. Their all located in a folder outside the project directory:

And for each directory there is an Include and Lib folders:

With windows and Linux library files:

And I am using MingW for the toolchain:

The issue I am having is the fact that My Cmake file is doing something wrong, I got the includes to work just fine but there is some issue with linking. My Cmake file below:

cmake_minimum_required(VERSION 3.6)
project(CL_GL)

set(CMAKE_CXX_STANDARD 11)

include_directories(${PROJECT_SOURCE_DIR}/../OpenGL/Lib_files/GLM/include)
include_directories(${PROJECT_SOURCE_DIR}/../OpenGL/Lib_files/GLEW/include)
include_directories(${PROJECT_SOURCE_DIR}/../OpenGL/Lib_files/GLFW/include)
include_directories(${PROJECT_SOURCE_DIR}/../OpenGL/Lib_files/SOIL/include)

set(GLEW_LIBRARY ${PROJECT_SOURCE_DIR}/../OpenGL/Lib_files/GLEW/lib/libglew32.a)
set(GLFW_LIBRARY ${PROJECT_SOURCE_DIR}/../OpenGL/Lib_files/GLFW/lib/libglfw3.a)
set(SOIL_LIBRARY ${PROJECT_SOURCE_DIR}/../OpenGL/Lib_files/SOIL/lib/libSOIL.a)


set(SOURCE_FILES main.cpp Shader.h Shader.cpp Camera.h Camera.cpp)
add_executable(CL_GL ${SOURCE_FILES})

target_link_libraries(CL_GL libopengl32.a ${GLEW_LIBRARY} ${GLFW_LIBRARY} ${SOIL_LIBRARY})

 

And when I try to compile the code I get these errors:

"E:\Program Files (x86)\JetBrains\CLion 2016.3\bin\cmake\bin\cmake.exe" --build "W:\GoogleDrive\OpenGL Projects\CL_GL\cmake-build-debug" --target CL_GL -- -j 8

....

 

Any idea what I am doing wrong?

Please take a look at the related StackOverflow discussion. Basically, something like the following should be enough:

set(CMAKE_PREFIX_PATH "path/to/glew")
set(CMAKE_LIBRARY_PATH "path/to/glew/binaries")
find_package(GLEW REQUIRED)
include_directories(${GLEW_INCLUDE_DIRS})
link_libraries(${GLEW_LIBRARIES})

OK got slightly further now but the issue I am getting is in the actual cmake creation:

Output:
