I am unsure as to why I am greeted with "fatal error: 'GL/glew.h' file not found" when trying to build. My CMakeLists.txt looks like this:
cmake_minimum_required(VERSION 2.8)
project(ex_1)
add_executable(TorusDraw.out TorusDraw.cpp)
find_package(OpenGL REQUIRED)
find_package(GLUT REQUIRED)
find_package(GLEW REQUIRED)
find_package(GLM REQUIRED)
include_directories( ${OPENGL_INCLUDE_DIRS} ${GLUT_INCLUDE_DIRS} ${GLEW_INCLUDE_DIRS} ${GLM_INCLUDE_DIRS} )
target_link_libraries( TorusDraw.out ${OPENGL_LIBRARIES} ${GLUT_LIBRARY} ${GLEW_LIBRARY} ${GLM_LIBRARY} )
It looks as though it also cannot find glm

Edit: I should mention the libraries were installed with homebrew

I'm trying to learn OpenGL from a tutorial, and I need to link SOIL2 to my project.
I tried to write my CMake like this:(all other libs are working, Cmake gets no error but I can't include SOIL2.h because of 'SOIL2.h' file not found). I'm working with Clion IDE.
cmake_minimum_required(VERSION 3.15)
project(OpenGL_Tutorial)
set(CMAKE_CXX_STANDARD 14)
add_executable(OpenGL_Tutorial main.cpp)
find_package(OpenGL REQUIRED)
find_package(SDL2 REQUIRED)
find_package(PkgConfig REQUIRED)
pkg_search_module(GLFW REQUIRED glfw3)
find_library(SOIL2 lib/libsoil2.a)
include_directories(
${OPENGL_INCLUDE_DIRS}
${GLEW_INCLUDE_DIRS}
${GLFW_INCLUDE_DIRS}
${SDL2_INCLUDE_DIR}
)
target_link_libraries(OpenGL_Tutorial
${OPENGL_LIBRARY}
${GLEW_LIBRARY}
${GLFW_LIBRARIES}
${SDL2_LIBRARY}
${SOIL2_LIBRARY}
)
libsoil2.a is located in my lib directory in the project directory
(see project direcory image)
Thanks!
I'm attempting to alter my CmakeLists.txt file for my currently working MacOSX version of my OpenGL engine, so that it will compile and run on windows. I'm positive that I'm doing something wrong in the way I'm writing my Cmakelists.txt and would like some help correcting it.
Have already tried a multitude of different tutorials and examples found online. The problem most likely lies in how I'm trying to link dll files but I'm unsure of what I'm doing wrong.

current error message happens when I cmake .
CMake Error at F:/glfw-3.3/src/CMakeLists.txt:95 (add_library):
add_library cannot create target "glfw" because another target with the
same name already exists. The existing target is a shared library created

In a few words I want to create a bunch of static libraries of the engine, in particular, link graphics library with GL's, and finally link all of them with the executable in a root CMakeLists.txt.
But I noticed that ${GLFW3_LIBRARY} is empty and I got a linker error, for example, when I call glfwInit(). I followed the guide during building and installation of GLFW
cmake .
make
make install
I believe headers and libraries are in /usr/local/*, but apparently CMake cannot find them or maybe I did something wrong.
The only hypothesis I have is that find_package doesn't know about glfw3Config.cmake which is in deps/glfw/*
I took the script from https://github.com/JoeyDeVries/LearnOpenGL/blob/master/cmake/modules/FindGLFW3.cmake and put it into cmake folder. Then in CMakeLists.txt I added
list(APPEND CMAKE_MODULE_PATH "${PROJECT_SOURCE_DIR}/cmake")
Now everything works properly
Thanks #Tsyvarev
I installed SOIL library for my C++ OpenGL project, but i always get
undefined reference to `SOIL_load_OGL_texture'
As I read from searching, It means that OpenGL is linking before SOIL. I don't know much about CMAKE, but right now my CMAKEFile looks like this:
cmake_minimum_required(VERSION 2.8)
project(game)
add_executable(game main.cpp ...(many files))
find_package(OpenGL REQUIRED)
find_package(GLUT REQUIRED)
include_directories( ${OPENGL_INCLUDE_DIRS} ${GLUT_INCLUDE_DIRS})
target_link_libraries(game ${OPENGL_LIBRARIES} ${SOIL} ${GLUT_LIBRARY})
set(CMAKE_CXX_STANDARD 14)
Your have to set SOIL to the SOIL library, and add also possibly use link_directories to add the path to the SOIL library.
I'm trying to familiarize with QGLViewer (http://libqglviewer.com/) so I installed it (on Ubuntu 14.04) and I'm trying to run the simpleViewer (which is a provided example). Now, the code can be built using qmake, but I want to compile the code with cmake so I wrote the following CMakeLists.txt:
cmake_minimum_required(VERSION 2.6)
PROJECT(simple_viewer)
SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake_modules)
FIND_PACKAGE(OpenGL REQUIRED)
INCLUDE_DIRECTORIES(${OPENGL_INCLUDE})
FIND_PACKAGE(QGLViewer REQUIRED)
INCLUDE_DIRECTORIES(${QGLVIEWER_INCLUDE_DIR})
FIND_PACKAGE(Qt4 REQUIRED)
INCLUDE(${QT_USE_FILE})
INCLUDE_DIRECTORIES(${QT_INCLUDES})
ADD_EXECUTABLE(${PROJECT_NAME} main.cpp simpleViewer.cpp)
TARGET_LINK_LIBRARIES(${PROJECT_NAME} ${QT_LIBRARIES} ${OPENGL_LIBRARIES} ${QGLVIEWER_LIBRARY})
I'm able to build the project but when I launch the executable this is the error I get:
dede#dede-P35V2:~/src/simple_viewer/build$ ./simple_viewer
*** Error in `./simple_viewer': realloc(): invalid pointer: 0x00007f64d34df840 *** Aborted
I'd be glad if someone could explain me what's wrong!
Thanks!
worked this way:
cmake_minimum_required(VERSION 2.6)

SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake_modules)

INCLUDE_DIRECTORIES(${OPENGL_INCLUDE})
