Mac - OpenGL - glew not found
<p>basically i try to figure out why compiler complains about missing glew-library:</p>

<pre><code>fatal error: 'GL/glew.h' file not found
</code></pre>

<p>My setup:</p>

<p>brew list:</p>

<pre><code>glew
glfw
glm
</code></pre>

<p>In /usr/local/include directory:</p>

<pre><code>GL -&gt; ../Cellar/glew/2.0.0/include/GL
GLFW -&gt; ../Cellar/glfw/3.2.1/include/GLFW
glm -&gt; ../Cellar/glm/0.9.8.3/include/glm
</code></pre>

<p>and Makefile:</p>

<pre><code># OBJS specifies which files to compile as part of the project
OBJS = *.cpp

# CC specifies which compiler we're using
CC = g++

# INCLUDE_PATHS specifies the additional include paths we'll need
INCLUDE_PATHS = -I/usr/local/include -I/opt/X11/include

# LIBRARY_PATHS specifies the additional library paths we'll need
LIBRARY_PATHS = -L/usr/local/lib -I/opt/X11/lib

# COMPILER_FLAGS specifies the additional compilation options we're using
# -w suppresses all warnings
COMPILER_FLAGS = -w

# LINKER_FLAGS specifies the libraries we're linking against
# Cocoa, IOKit, and CoreVideo are needed for static GLFW3.
LINKER_FLAGS = -framework OpenGL -lglfw3 -lglew

# OBJ_NAME specifies the name of our exectuable
OBJ_NAME = main

#This is the target that compiles our executable
all : $(OBJS)
    $(CC) $(OBJS) $(INCLUDE_PATHS) $(LIBRARY_PATHS) $(COMPILER_FLAGS) $(LINKER_FLAGS) -o $(OBJ_NAME)
</code></pre>

<p>When i have a file in same directory called: File.cpp and i run:</p>

<pre><code>make File
</code></pre>

<p>i get:</p>

<pre><code>fatal error: 'GL/glew.h' file not found
</code></pre>

<p>Can anybody explain why the above setup is wrong/damaged?</p>

<p>ps: os, el capitan</p>
