Unable to build GLFW with CMake errors

问题

I downloaded the latest GLFW source (3.1.1) from its site, uncompressed it to the desktop, and tried to build it with cmake. Some dependency errors popped up, but was quickly fixed. Until I got stuck on this one:

alex@alex-AMD:~/Desktop/glfw-3.1.1$ cmake .

-- Configuring incomplete, errors occurred!

I'm totally lost as to what this means, and how to proceed

I'm on Ubuntu 14.04 64 bit, with proprietary AMD Radeon 7950 drivers

回答1:

One of the error outputs was Looking for glXGetProcAddressEXT - not found, and the log files indicated that there was a linking error with libGL.

I then tried running apt-get install glfw to print out the list of dependencies. Even though it was an older version in apt-get, it still listed some dependencies that had to be installed.

GLFW compiled after installing libglu1-mesa-dev and libgl1-mesa-dev

The last error message CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: OPENGL_glu_LIBRARY (ADVANCED) was the one that threw me off. I thought it was a problem with paths and environment variables
