First of all - don't use file glob - see many past threads, FAQ
entries, etc. This is a common beginner mistake, with unfortunate
consequences.
Here is my quickie re-write of your build. You might need to
double-check the variable names with their respective find modules - I
did them from memory but with the knowledge that the OpenGL and GLUT
ones are a little funky when compared to the modern de-facto standard.
Main directory:
cmake_minimum_required (VERSION 2.6)
project(Pemberton)
find_package(OpenGL REQUIRED)
find_package(GLUT REQUIRED)
if(CMAKE_COMPILER_IS_GNUCXX)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Wextra -pedantic
-Werror")
endif()
include_directories(library ${OPENGL_INCLUDE_DIRS} ${GLUT_INCLUDE_DIRS})
add_subdirectory(library)
add_subdirectory(programs)
Library directory:
set(LIB_SOURCES Affine.cpp
Affine.h
Camera.cpp
Camera.h
Canvas.cpp
Canvas.h
Color.cpp
Color.h
Light.cpp
Light.h
Material.cpp
Material.h
Matrix.cpp
Matrix.h
Quaternion.cpp
Quaternion.h
Ray.cpp
Ray.h
Texture.cpp
Texture.h
utility.cpp
Vertex.cpp
Vertex.h)
add_library(myGraphicsLib STATIC ${LIB_SOURCES})
target_link_libraries(myGraphicsLib ${OPENGL_LIBRARIES} ${GLUT_LIBRARY})
Programs directory:
set(APPS exam
forces
ifs
lsystem
raytrace
subdivide
testray)
foreach(app ${APPS})
add_executable(${app} ${APPS}.cpp)
target_link_libraries(${app} myGraphicsLib)
endforeach()
Basic principles:
Mention anything only once.
Shared code: make a static lib
Don't use outdated commands or style (subdirs, all caps commands,
setting output directories without a compelling reason, using
add_definitions to sneak compiler flags in)
Minimize assumptions (-Wall -Werror only makes sense if you're
using the gcc suite)
Didn't test it, but at the very least it should get you close.
Hope this helps!

Hello everyone,
I am working on converting my project from using a handwritten
Makefile to using cmake.
I have been playing with cmake but I keep running into problems and
I'm probably writing really ugly CMakeLists.txt files.
My project is laid out like this:
graphics/
data/
bark.rgb
ground.rgb
leaf.rgb
library/
Affine.cpp
Affine.h
Camera.cpp
Camera.h
Canvas.cpp
Canvas.h
Color.cpp

Light.cpp
Light.h
Material.cpp
Material.h
Matrix.cpp
Matrix.h
Quaternion.cpp
Quaternion.h
Ray.cpp
Ray.h
Texture.cpp
Texture.h
utility.cpp
Vertex.cpp
Vertex.h
programs/
exam.cpp
forces.cpp
ifs.cpp
lsystem.cpp
raytrace.cpp
subdivide.cpp
testray.cpp
My "library" is all the classes that I use while the programs are each
files with a main function in them.
My code relies on Glut and OpenGl.
I would like cmake to build an executable for each of the files in
programs and preferably build out of source so things stay relatively
clean.
Here is what my CMakeLists.txt files currently look like and I have no
idea if I'm remotely doing the right thing.
In the root directory /
cmake_minimum_required (VERSION 2.6)
project(Pemberton)
find_package(GLUT)
find_package(OpenGL)
add_definitions(-Wall -Wextra -pedantic -Werror -O3)
SUBDIRS(library programs)
INCLUDE_DIRECTORIES(library)
set(LIBRARY_OUTPUT_PATH "${CMAKE_BINARY_DIR}/library")
set(EXECUTABLE_OUTPUT_PATH "${CMAKE_BINARY_DIR}/bin")
mark_as_advanced(LIBRARY_OUTPUT_PATH EXECUTABLE_OUTPUT_PATH)
In library/
FILE(GLOB SOURCE_FILES *.cpp)
FILE(GLOB INCLUDE_FILES *.h)
SOURCE_GROUP("Source Files" FILES ${SOURCE_FILES})
SOURCE_GROUP("Header Files" FILES ${HEADER_FILES})
ADD_LIBRARY (Graphics STATIC ${SOURCE_FILES} ${INCLUDE_FILES})
In programs/
include_directories(../library)
#FILE(GLOB SOURCE_FILES .*.cpp)
#FILE(GLOB INCLUDE_FILES *.h)
#SOURCE_GROUP("Source Files" FILES ${SOURCE_FILES})
#SOURCE_GROUP("Header Files" FILES ${HEADER_FILES})
find_package(GLUT)
find_package(OpenGL)
add_executable(lsystem lsystem.cpp ${GLUT_LIBRARY} ${OPENGL_LIBRARY})
#set(PROGRAMS ifs lsystem raytrace subdivide)
#set(CORELIBS ${GLUT_LIBRARY} ${OPENGL_LIBRARY} GL GLU)
#foreach(programs ${PROGRAMS})
# add_executable(${program} ${SOURCE_FILES} ${INCLUDE_FILES})
#target_link_libraries(${program} ${CORELIBS})
#endforeach(program)
What is the correct way to set this up? Currently it's saying it can't
find OpenGL functions. I would like to have some really nice clean
cmake files.
Best regards,
Craig
