CMakeLists.txt does not find OpenGL or OpenGLES

[svkatielee]

Compiling 4.4.0 openGL is not found by the CMake internal function and there is no find_package for finding openGLESv1 or openGLESv2.
I am compiling on Ububntu 15.04 64bit on Acer i7 laptop and armbian 5.14 Jessie 8 on Orange Pi PC.
On Jessie, I can force the top level CMakeLists.txt by adding: ( as per deltasig's posthttp://www.cruisersforum.com/forums/f134/opencpn-runs-on-embedded-arm-74082-56.html#post2095151 ) change:
# find_path(OPENGLESv1_INCLUDE_DIR GLES/gl.h )
SET(OPENGLESv1_INCLUDE_DIR "/usr/include/GLES" )
This finds the include files, but then fails to find the libraries in /usr/lib/mali/libEGL.so
So I linked them into /usr/include.

On the Ubuntu laptop, the libraries are in
/usr/lib/nvidia-352/ or
/usr/lib/x86_64-linux-gnu/mesa-egl/ or
/usr/lib32/nvidia-352/

Work-arounds are 'OK' sometimes, but isn't it time to fix CMakeLists.txt? I have tried for a few hours, but am having trouble following the logic there. It seems very convoluted.

With a little guidance I will try to come up with a patch for multiple arch's.

[seandepagnier]

what is the cmake output and log from a clean build directory? What exact change did you make to fix it?

For the Orange Pi, armbian 5.14 and Debian Jessie I changed the top CMakeLists.txt:
.... To that end I changed the CMakeLists.txt as follows in order for the Mali-400 to get in: about line 299
# find_path(OPENGLESv1_INCLUDE_DIR GLES/gl.h )
SET(OPENGLESv1_INCLUDE_DIR "/usr/include/GLES" )

then so it could find the lib to link I did this:
sudo ln -s /usr/lib/mali/libEGL.so /usr/lib/

Here is the cmake:

cmake has a built-in function: /usr/share/cmake-3.2/Modules/FindOpenGL.cmake

but it has no FindOpenGLES.cmake and opencpn has not written one yet either.

OOPs... I seem to be missing a lot of software packages on the laptop,
After finding one missing package at a time I finally went back and read the linux install instructions again. I missed the first step every time I that I had read that page...

I looks like it configures OK. It chose the mesa version of libGL instead of the nvidia version. Is that right?

I'll start the compile before bedtime and see in the morning.

Thanks Sean

Why can it not find /usr/include/GLES/gl.h? Any more hints by cmake?

then so it could find the lib to link I did this:
sudo ln -s /usr/lib/mali/libEGL.so /usr/lib/

/usr/lib/mali is non-standard if you wanted you could add it to the list opencpn looks for or do what you did.

Does opencpn work?  It sure looks like it found the  wrong opengl, but perhaps it doesn't matter so long as it uses the mali  version when opencpn actually runs...

You could write FindOpenGLES.cmake I didn't think it exists.
