Converting simple makefile into CMakeLists.txt? - makefile

Question

I'm trying to convert this simple makefile into a CMakeLists.txt. I'm specifically struggling with the flags.
SOURCE = triangle.cpp shader.cpp
CC = g++
CFLAGS = -Wall -Wextra -pedantic -framework OpenGL -framework GLUT -lGLEW -lglfw
OBJECT = window
default:
$(CC) -o $(OBJECT) $(SOURCE) $(CFLAGS)
clean:
rm -f $(OBJECT)
Here's my CMakeLists.txt:
cmake_minimum_required(VERSION 3.0)
project(Graphics)
set(CMAKE_CXX_FLAGS "-Wall -Wextra -pedantic -framework OpenGL -framework GLUT -lGLEW -lglfw")
#add_definitions(${CMAKE_CXX_FLAGS})
add_executable(
trtangle
triangle.cpp
)
Here's the error message I get:
Scanning dependencies of target triangle
[ 50%] Building CXX object CMakeFiles/triangle.dir/triangle.cpp.o

^~~~~~~~~~~
1 error generated.
make[2]: *** [CMakeFiles/triangle.dir/triangle.cpp.o] Error 1
make[1]: *** [CMakeFiles/triangle.dir/all] Error 2
make: *** [all] Error 2
I've also tried setting CMAKE_C_FLAGS But still no luck. Keep in mind when I use the makefile alone, everything compiles and works perfectly. I'm wondering if it's a GL error? or maybe I installed GLEW weirdly?

Answer 1

cmake
cmake_minimum_required(VERSION 3.0) # This line is required
project(triangle) # This line is required
make
CC = g++
CFLAGS = -Wall -Wextra -pedantic -framework OpenGL -framework GLUT -lGLEW -lglfw
cmake
set(CMAKE_CXX_FLAGS "-Wall -Wextra -pedantic -framework OpenGL -framework GLUT -lGLEW -lglfw")
make
SOURCE = triangle.cpp shader.cpp
default:
$(CC) -o $(OBJECT) $(SOURCE) $(CFLAGS)
cmake
# The name of the result and all required sources
add_executable(triangle triangle.cpp shader.cpp)
# These libraries are required
find_package(OpenGL REQUIRED)
find_package(GLEW REQUIRED)
find_package(glfw3 3.0 REQUIRED)
# ... and the path to the header files and so files
target_include_directories(triangle ${OPENGL_INCLUDE_DIRS} ${GLEW_INCLUDE_DIRS})
target_link_libraries(triangle ${OPENGL_LIBRARIES} ${GLEW_LIBRARIES} glfw3)
Other possibility is to collect all sources within a list at first.
set(SOURCES triangle.cpp shader.cpp)
add_executable(triangle ${SOURCES)
make
OBJECT = window
cmake
Not necessary
make
clean:
rm -f $(OBJECT)
cmake
This is built in.

Answer 2

cmake_minimum_required(VERSION 3.0)
project(Graphics)
add_executable(
trtangle
triangle.cpp
)
target_compile_options(trtangle PRIVATE -Wall -Wextra -pedantic)
find_package(OpenGL REQUIRED)
find_package(GLEW REQUIRED)
find_package(glfw3 3.3 REQUIRED)
target_include_directories(trtangle ${OPENGL_INCLUDE_DIRS} ${GLEW_INCLUDE_DIRS})
target_link_libraries(trtangle ${OPENGL_LIBRARIES} ${GLEW_LIBRARIES} glfw)
